Detectives investigating a sexual assault on an N29 bus have arrested a man.

In the early hours of Thursday April 19, a 26 year-old woman got on the bus at Trafalgar Square and fell asleep.

She awoke at about 2.45am when the bus was in Green Lanes, near Finsbury Park, to find the man sitting next to her was sexually assaulting her.

On September 16 a man aged 26 was arrested in connection with the inquiry at an address in Islington and taken to a north London police station.

He was bailed to return on October 5 pending further inquiries.
