Greater Manchester Police said three men and two women were arrested following reports of an assault on Portland Street. The incident took place at 4pm after Sir Iain had attended a fringe event on Brexit at the conference. The police said they believed there had been no injuries following the incident.
They added: “There aren’t believed to be any serious injuries, and following a short foot pursuit three men and two women have been arrested in connection with it, and remain in custody for questioning.
“Inquiries are ongoing.”
Afterwards, Sir Iain arrived at the Mercure Manchester Piccadilly Hotel where he joined Lord Frost for a debate on Brexit.
The former leader of the Conservative party said: “I’m glad to be here. I can honestly say that I nearly wasn’t here because I was assaulted by a bunch of protestors on the way here.”
He then explained to the audience he had been dragged from event to speak to the police.
He added: “That’s why the police were dragging me outside the door, I’m afraid.
“Anyway, it’s good to be here – I can genuinely say that more than the others on the panel!”
