A hessian bag was the latest item exhumed from a search area off Cobb and Co Road, not far from the home formerly owned by William's late foster grandmother and from where he disappeared in 2014.
The item was found by investigative search teams near the site where a piece of blue cloth was found on Friday. Both items have been bagged as evidence and will be sent away for forensic testing.
Ground penetrating radar equipment was used on the concrete slab underneath the home earlier in the week while the gardens below the balcony were excavated and the soil sifted.
