Three thugs threatened and racially abused a pregnant woman, punched a Tube passenger, and hounded other travellers.

The British Transport Police is investigating several reports of people being harassed on different parts of the Jubilee line on Saturday, December 2.

At around 4.30pm, it was reported that a pregnant woman was on a train when two of the three people began blowing vape smoke in her face.

When she asked them to stop, they threatened her and her baby and attempted to trip her up as she went to leave.

The group are reported to have made racist comments to the woman, believed to be Asian, as well as threatening to steal her shopping.

The group later began to make derogatory comments to another passenger and reportedly made “threatening gestures” to her friend.

As they got off at St John’s Wood station, one of the three punched the friend in the head.

At around 4.45pm, another Jubilee line passenger heading to Dollis Hill station was approached by three people, who the British Transport Police believe to be the same individuals.

One of the three suspects grabbed the victim’s phone and claimed it was now theirs.

They then harassed the victim, blocking her from leaving the train. Once she escaped, she called 999 but the suspects got off the service too and one of reportedly spat in her face as they got off the train.

Police believe that the three left the Underground at Neasden at 4.51pm.
