Police were left red-faced when a suspected chikan esacaped while being escorted to a nearby koban. A woman felt herself being groped on a morning commuter train and grabbed the man she suspected had committed the crime. She alerted staff at Nakano Station who contacted the police. Within moments, three officers arrived and two were asked to take the man down to the koban outside the station. At the ticket gate, the suspect shielded his face with his commuter pass - presumably to evade any CCTV surveillance - and sprinted into the rush hour crowd. He had a headstart of no more than a few metres but Tokyo's finest lost sight of him in the mass of commuters almost immediately. They are now looking out for a middle-aged, medium-build man wearing a suit. Police are investigating how their officers failed to keep the suspect in custody.
