Police are on the hunt for a man who allegedly performed a sex act on a bus while staring at lone women.

The man sat down on the top deck of the 192 bus from Manchester to Stockport and began whistling to try to get people’s attention.

When passengers looked at the man, they saw his private parts were exposed and he was ‘performing a sex act’.

Officers are now searching for an Asian male, who was around 40 years old, about 5ft 6in tall with a stocky build and wearing a grey wool hat and brown chinos.

Sgt Jon Kenna, from GMP’s city centre, team said: “We were called at about 12pm on Wednesday, March 1, to reports that a male on the 192 bus was sat on the top deck of the bus, whistling and trying to get people’s attention.

"It’s reported that when people looked at the male he was sat down, performing a sex act on himself, smiling, particularly at lone females.

"Clearly this is a very disturbing act to witness on a bus, where there are potential children who could have witnessed this incident.”

Anyone with more information should contact with police by calling 101, quoting reference 868 01/03/17 or calling Crimestoppers, anonymously, on 0800 555 111.
