A cash reward is being offered for information which leads to the arrest of Lincoln man Stewart Palmer.
The 39-year-old, of Yarborough Road, is wanted by Lincolnshire Police after being recalled to prison for breaching his licence conditions.
He was originally jailed for violence.
And a £100 reward will be paid to anyone who has any information which leads to his arrest.
Anyone who sees Palmer is asked not to approach him, but to contact DI Simon Lovett via the non emergency 101 number as soon as possible.
