Former local businessman Bill Spedding still appears to be the highest profile person at the heart of the search for three year old toddler William Tyrrell on the NSW North Coast.

Mr Spedding’s wife told Fairfax Media she was bewildered with the current rumours and speculation about her and husband.

‘’The community is unbelievable here they are supporting us and I understand many people in Wellington who knew Bill are astounded about the story.’’ Margaret Spedding said.

‘’I am surprised they are not looking elsewhere, we have nothing to do with this’’ she said.

Mr Spedding told media  it was “quite surprising” the search was taking place so close to his home.

However he understood the police and their line of enquiry.

“They’re only doing their job,” he said.

Detectives again arrived at the home of the tradesman  and former owner of Speddos in Wellington on Tuesday morning. Police were searching nearby bushland in relation to the disappearance of three-year- old William Tyrrell.

The head of the investigation, homicide Detective Inspector Gary Jubelin, arrived at the Bonny Hills semi-rural property a few minutes after Mr Spedding was seen leaving in his work van about 8.30am.

Police have repeatedly stressed the 63-year-old is not a suspect but a "person of interest" in relation to the suspected abduction of the toddler who vanished from his grandmother's Kendall home almost six months ago.

The local tradesman has come under intense media scrutiny after police spent 48 hours searching his Bonny Hills property and Laurieton office in January.

A number of items were seized including cars, computer equipment and a single mattress - all of which were sent for forensic testing. Police refuse to talk about the results.

No charges have been laid and two of Mr Spedding's children maintain their father has done nothing wrong and is distraught by the continued media attention.

Up to 30 officers will continue to scour a dense and muddy bush track about six kilometres from Mr Spedding's home and 20 kilometres from where the toddler disappeared in Kendall.

Police said the search came after fresh information was received in relation to William's disappearance and was expected to continue until Wednesday afternoon.

Detectives briefed the media on the search at a command post on Houston Mitchell Drive in the Queens Lake State Conservation Area yesterday afternoon and expected to continue their investigations on Wednesday.
