A man has been arrested in connection with an attack on a Conservative MP near Brighton as he arrived at a talk on squatting.
Mike Weatherley, MP for Hove in East Sussex, had rocks and tomatoes thrown at him as he attended the event at the University of Sussex on November 14.
He was invited to talk about his involvement in changing the law to criminalise squatting but was surrounded by a mob of non-students before the debate could start.
Security officials barricaded him and his staff in a room until the police arrived and took him away to safety in a van.
One of Mr Weatherley's team suffered a slight injury caused by a stone which had been thrown, according to police.
Sussex Police said that a 24-year-old man from Brighton was arrested on suspicion of affray and he remains in custody.
Mr Weatherley has been campaigning for squatting to be criminalised since his election to Parliament in 2010.
