The images of two men who pick pocketed a pensioner at Leeds station have been released by the British Transport Police.
The 77 year-old was travelling to London Kings Cross in January when two men apparently worked as a team to steal from him.
Police say the victim was distracted by one of the men while the train was in Leeds station as the other lifted the wallet from his pocket.
