INVESTIGATORS in search of William Tyrrell have shifted their focus to a new location, just four kilometres from where the three-year-old was last seen alive.

NSW Police confirmed that the new area of bushland comes “as a result of information uncovered during the course of the investigation”.

Search teams will now concentrate on bushland outside the forensic search area.

“Strike Force Rosann detectives identified an area of bushland at Cedar Loggers Lane and Batar Creek Rd, Batar Creek, as an area of interest to their inquiries,” police said.

Emergency services volunteers will also be involved in today’s search operation, which comes one day after what would have been the missing boy’s seventh birthday.

A police spokesperson told news.com.au that “at this stage we have not uncovered anything.”

She confirmed the search will continue all day today and tomorrow.

Channel 10 also confirmed a police dog has joined the search.

William was playing in the yard of his foster grandmother’s home on Benaroon Drive in Kendall, a town on the NSW mid north coast, 36 kilometres from Port Macquarie, when he went missing in September 2014.

Two weeks ago, investigators launched a fresh search for evidence for the boy who seemingly disappeared without a trace.

The ABC reported that since William went missing, police have identified almost 700 people of interest, conducted hundreds of interviews and gathered more than 4000 pieces of evidence.

A child’s toy along with other bags of evidence were collected on June 13 as the intensive search continued.

Speaking on ABC’s 7.30 on June 13, Detective Chief Inspector Gary Jubelin said there was 690 persons of interest when the $1 million reward was offered for information leading to William’s return in 2016.

William’s foster parents have always said they would never give up looking for him and still maintain hope he will one day be found.
