Officers investigating a racially aggravated incident on board the Northern Line are today releasing this image in connection.

Between 7.30pm and 8pm on Wednesday 28 February, a man was travelling from Bank to Golders Green when he challenged a passenger who was vaping on board the train.

The passenger then blew the vape smoke in his face, and made an anti-semitic comment to him.

The passenger, a man, left the tube at Golders Green and boarded another train.

Officers believe the man in the image may have information that could help their investigation.

Anyone who recognises him is asked to contact British Transport Police by texting 61016 or by calling 0800 40 50 40, quoting reference 677 of 28 February.
