Christopher Walker, 24, is black, slim, around 6ft with short brown hair.
He was last seen on Friday May 8, around 10:30am, at an address in Fuchsia Lane, Ipswich, wearing a white t-shirt and light blue jeans.
He has not been seen since and is breaching the conditions of his prison release licence.
Suffolk police say although he could still be in the Ipswich area, as he has links to Brixton, Lambeth and Rainham he may have travelled further afield.
Anyone who knows where Christopher is should not approach him but should call the police immediately by dialling 101.
Information can also be passed anonymously to Crimestoppers on 0800 555 111 if required.
