Merseyside Police is appealing for the public's help to trace 51 year-old man from Walton who is wanted on recall to prison.
Stanley Wilkinson, of Bushey Road, was sentenced to seven years and nine months for drug supply in 2009.
He was released on licence in July 2014 after serving half his sentence.
Wilkinson is wanted by officers after he failed to comply with his license release conditions and has been recalled to prison.
Extensive efforts have been made by the police to find him but he remains outstanding and officers are requesting the public's help to find him.
Wilkinson is described as white, 5ft 8in tall, with blue eyes, and short brown hair.
Anyone who has seen Wilkinson, or who knows of his whereabouts, is asked to call Merseyside Police on 0151 777 5439. People with information can also contact Crimestoppers, anonymously, on 0800 555 111.
