He spent fifteen years as a police officer before leaving the force after an incident of drink-driving in 2000. Dwyer had travelled to Weston-super-Mare with a colleague to interview a suspect before returning to Bridgend where he was due to meet colleagues. However, they never arrived and Dwyer remained in the pub longer than intended and, unable to find a lift home, he borrowed an unmarked police car from Bridgend police station to drive home. Believing he was under the limit, Dwyer fell asleep at the wheel and crashed the vehicle into a lamppost. He spent four weeks in hospital with broken ribs and was charged with aggravated taking of a police vehicle and drink-driving. Facing being dismissed from the force, Dwyer handed in his resignation.
