Tommy Robinson will not be charged over an alleged assault at St Pancras railway stations last month. 

The Crown Prosecution Service concluded ‘there was not a realistic prospect of conviction’, British Transport Police said. 

Following his arrest at Luton Airport, the 42-year-old was detained on suspicion of grievous bodily harm related to an incident that took place at St Pancras station on July 28.

The police force previously launched a probe after reports a man was assaulted at the busy London railway station. 

A day later, Robinson had gone to Tenerife and was wanted for questioning after video emerged of him walking away from the scene.

Stephen Yaxley-Lennon, known by his alias, was apprehended by law enforcement after arriving in Britain on a flight from Faro, Portugal, on August 4.

The authorities reported that they promptly gathered evidence, including eyewitness accounts and CCTV footage, but noted that the victim chose not to give a statement.

The CPS have now decided Robinson will not be charged after concluding ‘that [their] legal test for prosecution has not been met.’

Footage, released in July, showed Yaxley-Lennon, also known as Robinson, departing the site of the alleged attack at St Pancras railway station.

The video showed the far-right activist repeatedly pacing near a motionless individual lying face down on the concourse, which went viral online that month.

Earlier in the day, Robinson had shared footage of himself distributing flyers at the station, promoting an upcoming ‘free speech’ demonstration scheduled for September 13.

He later appeared to be walking in the background as security were called to help the unresponsive man.

One bystanders could be heard urgently shouting: ‘Can we get some help over here!’ 

But Robinson, visibly agitated, threw his arms in the air before turning and walking away down a staircase, repeatedly protesting his innocence. 

‘He f***ing came at me, bruv,’ he yelled in the clip. ‘He come at me bruv, you saw that.’ 

Robinson had also been active on his X account the same day, reposting a tweet which claimed he acted in self-defence. 

Today, the BTP, who did not name Robinson, 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. 

‘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 a file of evidence 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.’

A Crown Prosecution Service spokesperson said: ‘We received a file of evidence from British Transport Police in relation to an allegation of assault at St Pancras Railway station on 28 July.

‘Following a careful review of the evidence provided, we have concluded that our legal test for prosecution has not been met.

‘We have informed all parties involved of the decision.’
