Far-right activist Tommy Robinson has been arrested over an alleged assault at St Pancras train station in London.

British Transport Police stated that a 42-year-old man from Bedfordshire was arrested at Luton Airport on Monday in connection with an assault at St Pancras railway station on 28 July.

A spokesperson for the force said the arrest took place shortly after 6.30pm following a notification that a man had boarded an incoming flight from Faro, Spain.

“The man had been wanted for questioning after leaving the country to Tenerife in the early hours of August 29 following the incident at St Pancras,” they said.

“He was arrested on suspicion of GBH (Grievous Bodily Harm) and will now be taken to custody for questioning.”

Footage emerged last Monday appearing to show the activist, whose real name is Stephen Yaxley-Lennon, walking away from a man lying injured on the floor at St Pancras station.

Police said the man was taken to hospital with “serious” injuries that were not believed to be life-threatening.

Robinson was originally believed to have boarded a plane to the Spanish island early last Tuesday.

The victim is alleged to be an elderly man in his 60’s who is also a war veteran.
