Christopher Spelman, 57, was in 2014 convicted of a number of historic sex offences against a girl under 14 which happened in Carnforth.
As part of his notification requirements in line with his prison release, he was due to register at his new address in Cheshire which he failed to do.
Outside of Lancashire he has links to Liverpool, Staffordshire and Cheshire.
DS Angela Grey from the Sex Offenders Management Unit said: “We need anyone who may have seen Christopher Spelman or knows of his whereabouts to come forward.
“Spelman knows he should have gone to his new address to register and so I would also urge him if he sees this appeal to hand himself in at his nearest police station.”
He may have grown a full beard and is previously known to have camped outdoors.
