On Tuesday, 8 February, at around 14:40 on the bus route X140 travelling toward Harrow, a man was sitting on the bus and exposed himself through a hole in his trousers.
On Monday, 7 August, at around 18:35 on bus route 282 near Moat Farm Road, Northolt, believed to be the same man, was sitting on a bus and exposing himself in the same manner.
Officers are treating these two incidents as linked.
Sergeant Matthew Brown, from the Roads and Transport Policing Command, said: “I am asking anyone who recognises the man in this image to come forward and speak to the police. Exposure is treated as a serious offence and no one should be made to feel uncomfortable when simply using public transport.
“If you know this man, or have any information which could assist this investigation, please get in contact immediately.”
