Police are investigating after video of an antisemitic incident on a Tube train went viral.

Footage shared by The Campaign Against Antisemitism shows a passenger challenging a man vaping on board a Northern Line train between Bank and Golders Green on February 28.

The man then blows the vape smoke in the challenger's face and makes an antisemitic comment to him, British Transport Police said.

The victim of the abuse then 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.

Alternatively, contact Crimestoppers anonymously on 0800 555 111.
