Tommy Robinson will not be charged over an alleged assault at St Pancras railway station last month.
The British Transport Police said the Crown Prosecution Service concluded “there was not a realistic prospect of conviction.”
Police said that following an investigation, the alleged victim “did not wish to provide a statement to the investigation.”
Robinson, real name Stephen Yaxley-Lennon, was arrested at Luton airport on Monday 4 August, after leaving for Tenerife during the early hours following the incident on 28 July.
Video footage on social media showed the far-right activist walking back and forth near a motionless man lying on floor, near the escalator down to the Thameslink line.
The footage does not show how the man came to be hurt. However, Robinson appears to say: “He f***ing came at me, bruv,” before walking away down a set of stairs.
The activist said in a lengthy video on social media that he acted in self-defence after a man physically confronted him.
He urged the police to share the CCTV footage of what happened.
A statement from the force said: “Following a report of an assault at St Pancras station on 28 July, detectives from BTP quickly launched a full and thorough investigation, which involved a 42-year-old man being arrested on suspicion of GBH at Luton Airport on 4 August,” British Transport Police said.
“Officers worked at pace to gather evidence, including CCTV footage and witness statements, however the victim did not wish to provide a statement to the investigation.
“We presented the prosecution file to the Crown Prosecution Service (CPS) – who are responsible for considering the evidence available and deciding whether it meets the legal threshold to charge someone with an offence.
“Following a review of the available evidence, the CPS concluded that there was not a realistic prospect of conviction and therefore there would be no criminal charges in this case.”
