Three men chased a mugger into East Putney station in London, after he punched and kicked an elderly woman, but were turned back at the barrier because they had no tickets, it was stated at the Central Criminal Court yesterday. They were refused use of a telephone to call the police, so they bought platform tickets, went into the station and caught the attacker, a youth of 17. One of the pursuers had to go outside to make a 911 call. Mr Justice Melford Stevenson said the incident deserved to be brought to the attention of the railway authorities. He sent the mugger to jail for five years. Terry Tailor earlier had admitted assaulting Mrs Margaret Percy, aged 67, with intent to rob her.
