A man who indecently exposed himself to women on two London buses blocked the path of one so she could not leave. 

The first attack happened on the route 31 in Belsize Park at about 8am on September 8.

The female victim boarded the bus at Avenue Road where the suspect sat directly behind her.

When she looked at him, she could see that he was indecently exposing himself.

The suspect then put his foot out in front of the victim to stop her from leaving the bus, Scotland Yard said.

The second incident happened at 4.37am on Tuesday, November 7.

The victim boarded a bus at Victoria Street, Victoria, and travelled on the bus route 170 towards Roehampton where she saw a man indecently exposing himself with his phone in his hand.

When she shouted at him, the suspect replied “do you have a cigarette?”.

The Metropolitan Police have released two images of a man they would like to speak to in connection with these incidents.

He is described as having dark coloured skin, a black beard and long hair which has been tied back or with a black headband.

In one image he is seen wearing a black coat with a hood pulled over his head and in the other image, he is wearing a dark green jacket and light coloured trousers.

Det Sgt Matthew Brown, who is leading the investigation, said: “Nobody should ever have to witness indecent exposure and experience this abhorrent crime when travelling on London’s bus network.

“We remain absolutely resolute in our commitment to protect women and girls across London.
