Wednesday 2.20pm: A fibro cabin in a caravan park at Laurieton has been searched by police investigating the disappearance of toddler William Tyrell after residents reported hearing cries of a child in the weeks after the three-year-old vanished.
Police searched a cabin at The Haven caravan park at Laurieton, just south of Port Macquarie at the end of last week.
The cabin is one of many properties searched since the three-year-old disappeared from his grandmother's home in the neighbouring town of Kendall on September 12.
Revelations of the caravan park search come after homicide detectives raided a home at nearby Bonny Hills and a unit above a set of shops at neighbouring Laurieton on Tuesday, seizing a mattress and computer equipment.
The owner of the caravan park told Fairfax Media that a resident had called police after hearing a child crying in a cabin where a middle-aged couple from Victoria stayed from September 28 to October 9.
"They heard an infant crying and they thought it was coming from that cabin," the owner said.
"We don't have kids, [nor are there] many children in the park; they are all retired here, so it is an unusual sound," he said.
"Police came here. They wanted to have a look through even though I'd been through that cabin since. We went down because obviously there might have been a body in there or [the police] thought there could be."
The owner said he gave the address of the couple to police and "away they went".
Wednesday 1.30pm: Bonny View Drive resident Kylie, who did not wish to give her surname, said the sound of officers arriving for Tuesday's raid was unmistakable.
"They didn't need their sirens there was that many of them," she said.
More than 15 cars poured into Wandaloo Place from 5am on Tuesday.
"They blocked off both sides of the street and even though they were in suits, we knew something was up," Kylie said.
Wednesday 12.30pm: A senior police source has confirmed investigators will return to the Wandoo Place house on Thursday.
More forensic specialists are expected to arrive, with particular attention being paid to the area from the septic tank opening to the former woodpile site.
Wednesday 11.30am: Three generations of Linda Collins' family live in the neighbourhood being searched.
Mrs Collins said while many in the area mix socially, she hasn't seen much of those living in the house on Wandoo Place.
"You never really see them. I've never seen kids playing in their yard."
The grandmother has been a resident of the area for three years.
The neighbourhood's annual Australia Day party was to be hosted at Mrs Collins' Jolly Nose Drive house next week.
She said she'd dropped a leaflet at the Wandoo Place residence, "but we weren't expecting them to come along".
Wednesday 11.20am: John White has lived in the Jolly Nose neighborhood for 15 years, and he's never seen anything like what's unfolding around the corner.
"This is a great little neighbourhood," the retiree and avid lawn bowler said. "That's why this whole situation is so strange - everyone here gets along brilliantly."
Mr White and his wife regularly leave the area for trips in their caravan.
"We know people will look after our place while we're gone. We love it here. We've never had any problems."
Wednesday 10.30am: Following the drainage of the septic tank, there is a reduced police presence at the house on Wandoo Place, Bonny Hils.
Detectives from the Mid-North Coast are supervising two forensic officers as they use an excavator to clear a large wood pile.
Wednesday 10.15am: The police presence at Bonny Hills and Lake Cathie is significant as the search for missing toddler William Tyrell has taken a new turn.
A PolAir chopper is hovering above Lake Cathie while an excavator has cordoned off a semi-rural property in Wandoo Place, Bonny Hills,, where an elderly couple live.
A grease trap and septic service truck pulled up to the house about 8am on Wednesday.
Homicide detectives have spent more than 24 hours searching through the single-level house in Wandoo Place, Bonny Hills, just south of Port Macquarie.
A complicated family history prohibits the missing three-year-old's parents from speaking publicly about William’s disappearance, but Superintendent Paul Fehon said they were being kept up to date with the investigation.
Wednesday 8.30am: Police are emptying a septic tank at a Bonny Hills home as they continue to seize forensic evidence in relation to the disappearance of toddler William Tyrell.
Homicide detectives have spent more than 24 hours searching through a Bonny Hills home, just south of Port Macquarie.
Officers have cordoned off the semi-rural property, and a grease trap and septic service truck pulled up to the house about 8am on Wednesday.
Detectives were instructing a man and he was later seen putting a large hose into the ground near the front of the single level home.
An elderly couple live at the semi-rural property and are believed to own a business that was raided at the nearby town Laurieton on Tuesday.
Computer equipment and a mattress were seized from an office space above a set of shops and taken away for forensic testing.
Resident Dean Pollard said the couple who owned the house on Wandoo Place are the guardians of at least three grandchildren.
He said at least 20 police officers and six cars were parked outside the home since 7am on Tuesday.
Next-door neighbour Hannah-Jayne, 18, said she was deeply disturbed that police were searching the couple's home in relation to the toddler's disappearance.
She told Fairfax Media she did not know the couple that well but said one of their grandchildren often played with her dog Wilfred.
"It's really scary," she said. "I hope they find him [William] soon, just hopefully not next door to my house."
Another neighbour said she had met the man and two of his grandsons for the first time at a street Christmas party last year.
It is believed the couple rent the property and moved in a few years ago, neighbours say.
The couple are believed to own a business at the nearby town of Laurieton that was raided on Tuesday.

Homicide detectives raid properties searching for evidence
Homicide police have raided properties on the state's mid-north coast in the search for missing toddler William Tyrell, with detectives now almost certain the three-year-old was abducted.
It is understood computer equipment and a single mattress was seized from a unit in Laurieton, south of Port Macquarie, searched as part of the ongoing investigation into the little boy's disappearance four months ago.
The items are expected to undergo urgent forensic examination as police continue their inquiries.
Police sources have told Fairfax Media it is most likely the three-year-old was abducted.
"We don't think he has just wandered off somewhere," a senior officer said.
William vanished without a trace from his grandmother's Kendall home, just south of Port Macquarie on September 12.
He was wearing a Spiderman suit and playing in backyard with his sister when he disappeared, as their mother made a cup of tea.
On Tuesday, detectives from Sydney travelled to the neighbouring suburb town of Laurieton to search a unit above a set of shops.
Up to a dozen detectives and forensic officers spent several hours searching the unit on the corner of Bold and Seymour streets.
A local employee who works in a shop beneath the units said the police spent most the day searching the premises.
"They've been here all day from what we could tell – just forensic people here all day," the man, who did not wished to be named, said. "They left this afternoon and took a whole lot of things with them. The detectives have been in and out all day, up and down the stairs."
The man said he believed a man and woman lived in a unit above the set of shops but said he had never seen anyone in the office space where police had focused their investigations.
"They were looking through the office."
It is understood a number of people were interviewed on Tuesday as part of the ongoing investigation into the toddler's disappearance.
"Today police are searching a number or premises and speaking with numerous people as the search for William Tyrell continues," a NSW Police spokesman said.
Fairfax media understands homicide detectives, along with local police from the Mid-North Coast have searched a number of properties in recent months.
A 10-kilometre search of the area surrounding the house failed to find any trace of William.
The search lasted weeks and involved the NSW Police, Rural Fire Service, the State Emergency Service and more than 200 locals.
Investigators have searched every corner of the 21 houses in the bushland estate where William was last seen.
Commander of the Mid-North Coast region Superintendent Paul Fehon has recently said police were will looking at a number of scenarios.
Superintendent Fehon said that, if the little boy had some form of misadventure in nearby bushland, police would have found something by now.
"We are completely open to any possibility, including human intervention," he said in an interview with Fairfax Media. "If that has occurred, somebody knows something."
He said police have sifted through hundreds of pieces of information that poured into Crime Stoppers, but still have no solid lead.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
