Police have cautioned a man for masturbating on a Croydon bus.

The 32-year-old was arrested on Thursday after being identified from CCTV footage performing the sex act on the 64 bus from Thornton Heath to New Addington.

He was seen masturbating by another passenger on the bus, on which he travelled from East Croydon to South Park Hill Road in South Croydon, at about 11pm on February 9. 

He admitted indecent exposure following his arrest last week.

His arrest was one of 29 made in Croydon during Operation Big Wing, a day of police action largely targeting offences such as burglary and theft.
