A Conservative MP claims he was attacked by protesters on a visit to the University of Sussex.
Police confirmed they took Mike Weatherley to safety in a police van but said there were no reports of any injuries.
Mr Weatherley said in a statement: “It’s absolutely outrageous that a peaceful event such as this should be hijacked by a group of violent thugs.
"As soon as I walked in to the lecture theatre someone attempted to punch me.
"The event was immediately abandoned, but as we tried to leave, rocks were hurled, and two female members of my staff were injured.
"My staff and I were barricaded into a room, until the police arrived.”
