Detectives are appealing for information after a family from Barnet was racially abused on the Tube.

British Transport Police (BTP) has released an image of a woman they want to speak to in connection with the incident which happened on board a Northern line train.

A 31-year-old man from Barnet boarded the Tube at Tottenham Court Road on Saturday, November 30 2013 with his wife, who was carrying their young child.

As a passenger offered his seat to the victim’s wife, another female passenger complained, making racially abusive comments towards the family.

Two men, who were travelling with the woman, then grabbed the victim by his shoulders and pushed him.

The group, who all spoke with a Midlands accent, left the train at Euston where they are believed to have travelled on a train to the West Midlands.

One of the suspects is described as a white man, with stubble, around 5ft 6ins tall and stockily built.

He is believed to be in his late 40s and was wearing glasses at the time.

Detective Constable Dick Mortimer said: “This was a busy train and we believe there will be a number of people who witnessed what took place.

“If you were on board the service at the time, we urge you to come forward as you may have information crucial to our investigation.

“If you recognise the people pictured, or have any information that you think will assist officers, please contact us on 0800 40 50 40, or text 61016.”
