Two Labour campaign workers were arrested and suspended from the party following an attack which left a man in hospital with head and facial injuries.
The incident happened as party workers were handing out balloons in the High Street of Brierley Hill in Dudley, West Midlands, on Saturday. It is believed that the victim, aged in his 40s, was walking along the road with his elderly mother when he ripped down a Labour poster outside the local campaign office.
