Police have seized a white station wagon from the home of a person of interest in the disappearance of NSW toddler William Tyrrell.

9NEWS understands the car was taken by police from the home of convicted pedophile Tony Jones on September 16.

Jones, 59, was sentenced to three years jail yesterday after pleading guilty to the indecent assault of a child. The child involved was not William.

Jones was a member of a grandparents social group and is a former neighbour of Bill Spedding, another person of interest in the case.

No one has been arrested or charged over William’s disappearance on September 12, 2014.

Police issued an appeal for information into these cars seen in the area on the morning William disappeared. (60 Minutes) (60 Minutes)

The three-year-old had been playing in the backyard of his grandmother’s home at Benaroon Drive in Kendall on the NSW mid-north coast when he vanished.

Earlier this month police issued an appeal on 60 Minutes for information into four cars seen in the area on the morning William disappeared.

One of the cars they were searching for was a white station wagon.

The car seized is currently being examined by forensic investigators.
