Tommy Robinson has been released on bail after being arrested on suspicion of assault.
The former English Defence League leader was detained after police received a report of an assault on a man at Hollywood Retail Park in Barrow-in-Furness, Cumbria, shortly after 8.30pm on Thursday.
The 37-year-old was also questioned in custody on suspicion of a public order offence.
He was questioned along with a 43-year-old man from the West Midlands area, a 47-year-old man from the North Wales area and a 28-year-old man from the Bedfordshire area.
Footage shared on social media shows Robinson, whose real name is Stephen Yaxley-Lennon, filming himself and then police officers who arrive at an address in the town.
Robinson explains to an officer that he “acted in self-defence” after he says that someone spat in his face.
On Saturday morning, Cumbria Police said the four arrested had been released on bail and appealed for witnesses to come forward.
Robinson, from Luton, has made two trips to Barrow within the last fortnight and says he is working as a journalist to investigate claims of what he terms may be “a Muslim grooming gang” operating in the town.
