A thief stole from a man he befriended after the victim fell asleep at Leeds railway station.
The crook saw his opportunity to pinch the 24-year-old man’s phone, cash and bus pass when he nodded off after a night out.
PC Katalin Zelei, of British Transport Police, said: “The victim spent the night out drinking in Leeds and was befriended by a man at a city centre bar.
“They walked together to Leeds station, as they both planned to get a train back to Huddersfield that night.
“Once at the station, the victim fell asleep outside Leeds Visitor Centre while waiting for his first train home.
“At approximately 2am, the other man removed the victim’s phone from his pocket, along with a £20 note and bus pass.
“The victim reported the theft to BTP when he woke up, several hours later.”
Officers have now released CCTV images of a man they want to speak to about the incident, which happened on Wednesday, November 5.
PC Zelei added: “Who is the man in the beanie hat? That’s the question I need help answering. If you recognise him, please get in touch, as I believe he has important information about what happened.”
