A man who sexually assaulted two women on the Tube has been sent down for three years.

Nasser Chawki, 28, sexually assaulted a woman by rubbing himself against her on a busy Southbound Victoria line train traveling between Seven Sisters and Finsbury Park.

On a second occasion, Chawki rubbed himself against another woman on a rush hour Eastbound Piccadilly line train between Piccadilly Circus and Leicester Square.

Chawki was arrested again for possessing a forged French ID document before cops traced the sex attacks back to him.

"Disgusting behaviour"

He plead guilty last week at Southwark Crown Court to two counts of sexual assault and possession of a forged ID document.

DC Jane Hill called Chawki’s behaviour "disgusting." CCTV was crucial to nailing Nasser as officers were able to see where he entered the underground network and study his travel patterns allowing an easy arrest.
