A suspected former secret service agent, Travis Reinking, 29, shot dead four persons and injured four others, at a restaurant, at Nashiville of Tennesse in United States of America (USA). The gunman, who barged in with just a coat on, ran away naked, after another person overpowered him and snatched his gun. Police are on the chase, in helicopters. He was identified as Travis Reinking, after detectives found his abandoned car at a distance from the restaurant. Earlier last year, Travis was held and divested of four guns from his possession, when he was spotted at a public meeting.
