Hundreds of Tommy Robinson supporters flocked to Downing Street on Saturday to demand the release of the far-right leader.
Robinson, 35, was arrested on suspicion of breaching the peace on Friday after he was seen filming outside a court house.
It has caused a furious backlash among his supporters who stormed Whitehall on Saturday to stage a protest.
They waved '#FreeTommy' and 'Free the truth teller' placards as others branded St George's flags and banners with 'Make Britain Great Again' on them.
Some managed to mount the gates surrounding the Prime Minister's home, but the Metropolitan Police told MailOnline there were no arrests made.
