Police divers have scoured a dam as detectives continue in their hunt for William Tyrrell's remains. A pair of police divers entered the dam on private property near the main search area about 10am on Thursday. The two divers will search the water for any clues before making their way through a clearing back toward Batar Creek Road, where officers are still raking through soaked soil. The specialised officers first arrived at the Batar Creek Road dig site in Kendall on the NSW mid north coast on Wednesday afternoon, where they inspected a rainwater tank at the home where William was last seen.

It's understood the team will also be required at the primary dig site just 700m down the road on Thursday. One creek in the zone has already been drained as detectives and RFS crews continue to search for William. They're holding out hope his loved ones - and the public - will have closure by the end of the search. But what initially was expected to take two to three weeks is looking more likely to drag on well beyond a month as detectives expand the scope of the search to a one square kilometre radius. William Tyrrell (pictured) vanished from his foster grandmother's house in Kendall, on the NSW mid north coast in 2014 sparking an enduring police investigation Last week, police revealed they were investigating whether William fell from the balcony at his foster grandmother's home to his death. While the majority of the taskforce combed through bushland at the main search site on Batar Creek Road, a handful of officers were seen connecting a hose to the water tank. It’s not clear if the tank was drained in the initial search for William when he disappeared seven years ago on September 12, 2014. Within an hour, the dive crews had finished their inspection of the tank and left site. The home, once owned by the young boy's foster grandmother, now belongs to a man who has nothing to do with the case. Members of the police dive squad lowered a GoPro-style camera fitted to a pole into the tank to film what was inside His foster grandmother's house (pictured) where William was said to have been playing outside before he vanished He never came out to greet police or inspect what they were doing to the water tank, and it's understood he's handled all the upheaval and constant interruptions with grace. William's foster grandmother was under no legal obligation to declare the grim recent history of the home to the new owner and her identity, like those of William's foster parents, was suppressed. Last Monday, dozens of officers descended on the new owner's home and told him they were investigating whether William's remains could be on or near the property. For the second time since moving into his quiet, peaceful dead-end road toward the back of Kendall, the new owner of the home – who Daily Mail Australia has chosen not to name – found himself at the mercy of detectives simply doing their jobs. 'I feel really, really sympathetic for him,' one local who has lived in town all his life said. 'I just am really sorry for him.' The man has spent the last 11 days holed up inside with only the company of his pet Rottweiler, occasionally stepping out to run errands. Forensic officers and detectives used their hands to sort through dirt unearthed by a digging machine The back verandah (pictured) of the house has a five metre drop to the ground - which has recently been inspected by police He has tried to keep a low profile as reporters camp out the front and police traipse through his property hunting for clues. A specially trained cadaver dog was brought in to search underneath his home for evidence, his garden bed has been dug up and a concrete slab laid in the garage of the home was scrutinised by the Australian Federal Police using a ground penetrating scanner. The AFP's Forensic Imagery and Geometrics team looked into any abnormalities under the slab by bouncing an image off the machine's radar. He, like his neighbours and the wider community, are said to be hopeful that this search will yield a different result than in the past.

'We all want William found and to put him to rest if that's what it's come to.' But the reinvigorated search has others on edge. It's not the first time they've heard whispers of a breakthrough in the case, and many are wary of getting their hopes up again. Police revealed new information had led them back to Kendall, and three dig sites identified as potential covert burial sites have become the focus of their efforts.
