Wrexham muggers flee after shouts from member of public 26 May 2013 Last updated at 16:34 Three hooded men fled from an attempted mugging in Wrexham after a member of the public intervened. Police say it followed a bid by the men to rob a 17-year-old of his mobile phone at knife-point. The incident happened at Holt Road between 22:35 and 22:50 on Friday evening. As the muggers threatened the teenager, a passer-by shouted at them to "leave him alone." Police said they are searching for the attackers. This was an unprovoked attack on a young male. This is not a common occurrence in Wrexham," said Det Sgt Kevin Bowden. The teenager suffered minor injuries in the incident, after his attackers fled empty-handed. North Wales Police have appealed for any witnesses to come forward, including the member of public who intervened to prevent the robbery. Anyone with any information is asked to contact the police on 101.
