Police are hunting a woman they suspect punched a teenager, racially abused a passenger and threatened to push her under a tube train in two ‘distressing’ assaults.

Officers released an image yesterday of a woman they want to speak to after an attack at Morden station which has been linked to an assault in Stockwell.

At Morden station, police said a 19-year-old woman was barged into on the station stairs.

PC Eric Anang of British Transport Police said she spoke politely to the woman who had bumped into her but, instead of apologising, the woman attacked her, punching her in the face before boarding a train.

Wimbledon Guardian:

PC Anang said: "While the victim was not seriously injured, she was understandably distressed by the assault."

The incident took place on Friday, May 2, at about 8.20am.

Months before on Thursday, March 27, at 8.45am, a woman was waiting on the busy northbound Victoria Line platform at Stockwell station and asked a woman behind her to step back so she could move away from the platform edge.

PC Anang said: "Another woman took offence to the request and began shouting racist abuse at the victim, threatening to push her in front of an approaching train.

"She then followed the victim onto the train and attacked her.

"Other passengers dragged the woman away from the victim, who managed to get off the train at Victoria, but was left bruised and shaken by the attack."

Officers now believe the woman who carried out this attack was responsible for the assault at Morden station.

PC Anang said: "I believe the woman in the images we are releasing can help with our enquiries into both incidents.

"If anyone recognises her I would ask them to contact us."
