A Mecklenburg County judge denied bond for Tommy Martin, who is accused of pushing a Charlotte light rail security guard onto the tracks and attacking her at the Arrowood station. Martin remains in the Mecklenburg County Jail after the judge, Roderick Davis, found that no conditions could reasonably ensure Martin’s court appearances and protect public safety. According to an arrest affidavit, the guard recognized Martin from an earlier encounter and asked him to leave the station and show a transit ticket. After he refused both requests, she took out her phone to photograph him, the affidavit states. Martin allegedly shoved her onto the tracks, where she hit her head. The guard radioed for help during the incident, saying she had been pushed onto the tracks and was bleeding. Court records further allege Martin took her cellphone, threw four rocks at her while yelling obscenities, searched her pockets and stomped on her legs as she tried to defend herself. The allegations have not been proven in court. Martin is presumed innocent unless found guilty. The attack has renewed attention to security on Charlotte’s light rail system. Walter Kimble, a security consultant and former police chief, said transit security workers play an important role in public safety, particularly in areas considered higher risk. He also said riders need to feel secure, not simply be told that a location is safe. In the months after the killing of Iryna Zarutska, the Charlotte Area Transit System added security guards employed by contractor PSS. Off-duty Charlotte-Mecklenburg police officers were also offered the opportunity to patrol light rail stations and the Rail Trail. Data from June showed overall crime on the Blue Line had fallen nearly 70% compared with the same period a year earlier, though some riders continued to express safety concerns.
