Robert Edward Hind was reported missing at 9.30am on Wednesday after he absconded from an address in Dewsbury.
Hind, who is also known Dack, is a known sex offender who presents a risk to the public, particularly children.
DCI Paul Jeffrey of Kirklees Police said: “We believe he remains in the West Yorkshire area and may have travelled to Huddersfield. He does, however, have connections in the Lancashire area.
“Extensive enquiries have been conducted to trace him and these are continuing. His details have also been circulated to other Forces.
“It is likely that he is using public transport to get around and I would urge members of the public to let us know immediately if they believe they have seen him.”
Hind is described as slim, around 5’8” tall, with brown hair, green eyes and has a distinctive scar on his neck.
He was last seen wearing a dark hat and a green jacket with oriental style writing on the back.
Anyone who see Hind should not approach him and call 999 immediately.
