Police are hunting a prisoner who was released from jail in error.
Ryan Byrne, 34, was mistakenly freed from Wandsworth Prison in south London, Scotland Yard said.
Officers in Hammersmith and Fulham, west London, are looking for Byrne, who is described as white, 5ft 11in and of medium build. He has blue eyes and a goatee beard.
A Yard spokesman said police were informed by the Prison Service on Friday that Byrne had been released in error.
Anyone who has seen Byrne or has any information on his whereabouts is asked to contact police on 101.
A Prison Service spokeswoman said: "Releases in error are very rare but regrettable occurrences. The number of incidents have fallen significantly in recent years with figures down by a quarter compared to 2009/10 but every incident is taken extremely seriously and we are not complacent.
"We are investigating this incident. The recapture of this prisoner is now a matter for the police."
