A man has threatened a pregnant woman on a train, prompting police to release CCTV images of someone they would like to speak with.

The British Transport Police (BTP) yesterday (July 1) launched an appeal to find a man in connection with aggressive behaviour on the London Underground in Barking on May 26.

At about 10.45pm that day, two women were going eastbound on the district line when a man sat down and knocked into one of them, a pregnant woman.

He spilled a drink on himself, police said, and was reportedly told to mind what he was doing.

Police said he then became abusive towards her and another woman by making threats and shouting derogatory comments at them.
