A man dressed as a suicide bomber has been criticised by British Transport Police as "insensitive and crass" after boarding the Tube at rush hour.
The individual was travelling on a District Line train he caught at Fulham at around 7pm on 18 January, accompanied by friends in fancy dress as policemen.
A spokeswoman for British Transport Police said: "While this incident was not reported to us by anyone on the train, it is insensitive and crass behaviour in the light of recent terrorist attacks across the world and the threat to the UK, currently at severe.
"It is important for everyone to remember the need to be responsible and considerate to fellow passengers while making your journey.
"We would always encourage anyone to report anything they think is suspicious or which makes them uncomfortable to us, to allow us to establish if any further action is needed."
The stunt was snapped by a fellow commuter, who posted a picture of the incident on Twitter, causing others to tweet condemnations of the man's actions.
