Lincolnshire Police are offering a £100 reward to anyone who can help with information leading to the arrest of a wanted man.
Shane Atkin (21) (pictured) is wanted in relation to the attempted theft of a motorbike from the back of the Waterside Shopping centre in Lincoln on October 13.
He is also wanted on a recall to prison for breaching licence conditions. His original offences were grievous bodily harm and an unlawful escape from custody.
Atkin is thought to still be in the Lincoln area.
Officers are asking members of the public to call the police immediately if they know where he is living, or have seen him recently.
People can talk to Lincolnshire Police directly (0300 111 0300), or give information anonymously via charity Crimestoppes (0800 555 111).
