A 21-year-old man from Brighton is wanted by Sussex Police for recall to prison.
Tyler Boarer, of Downash Close, Whitehawk, is accused of breaching the conditions of his release licence.
He was jailed for three years in August 2010 along with four other members of a drugs gang who had been supplying heroin in the Stanley Road area of Brighton.
Sussex Police said that he was recalled to prison on Friday 15 February but was seen in Brighton on Wednesday (12 June).
He was described as a stocky 5ft 9in tall white man.
A spokesman said: “He is not deemed to be a risk to the public.”
Anyone with information about Boarer’s whereabouts is asked to call Sussex Police on 101 or the independent charity Crimestoppers anonymously on 0800 555111.
