It was reported on 17 April 2008 that Richards had been arrested in connection with an alleged assault on a Conservative party worker. He was later released after receiving a caution from police. Richards became angry when the councillor, who was canvassing door-to-door, told him he hadn't been sent promotional literature as he was already listed as a prominent party member. When later asked about the incident, Richards said that he gave the young councillor, who was "half his age and twice his size", a "clip around the ear" for "being cheeky". He attributed the incident to lack of sleep.
