Police have released images of a man they would like to speak to after a teenage girl was "brazenly" sexually assaulted on a bus.
The girl, 14, was sexually assaulted on a 140 bus in Harrow, police said, and the force have released images of a man they would like to speak to in connection with the incident.
It was the second of two sexual assaults that day, police said, taking place at around 8am as the bus was travelling towards Harrow Weald on September 27.
A man first assaulted a woman, then soon after assaulted the girl, 14.
Detective Constable Charlotte Joseph said: “No woman or girl should face this kind of behaviour when simply trying to use public transport.
"I want to commend her bravery for recognising this behaviour was wrong and reporting what happened to police."
“Our investigation shows that prior to the assault on a 14-year-old the man did a similar thing to another woman.
"From our records, it does not appear that this was reported to police and we would encourage her to come forward.
"In both circumstances the man trapped the victim so she cannot move away from him and brazenly carries out his attack in broad daylight on a bus full of people.
“These are incredibly clear images and I am confident that someone would be able to identify who this is.
"It is really important that we speak to this man as part of our investigation,” she added.

The girl, 14, was stood in the area marked for disabled passengers near the stairs.
A man, described as in his 50s with glasses and moustache, moved to stand near her.
He trapped and prevented her from moving then touched her inappropriately twice, police said.
The girl pushed past him as other passengers moved to get off the bus, and reported him to the police.
Police found CCTV footage which showed the man assaulting a different woman in the same manner before assaulting the girl.
