A convicted child sex offender who is believed to have links with a Kent town is being hunted by police.

Following a national appeal on the BBC programme Crimewatch, police in West Yorkshire renewed their calls to help find Stuart Smith.

The 66-year-old is thought to have links with Folkestone as well as several other places including Sheffield, Grimbsy and Pontefract in Yorkshire.

He is considered to be dangerous and pose a serious risk to children. Police are hunting him as he has failed to tell them where he is currently living.

But he is known to travel around the country especially on trains but also may be driving a red Ford Ka with the registration YL07 NKK.

Detectives are advising members of the public to contact them straight away if he is seen.

Anyone with information should call West Yorkshire Police on 01924 878 368 or call Crimestoppers anonymously on 0800 555 111.
