BAD IDEA OF THE WEEK: Subway attacks

A man has been pushed to his death beneath a train on the New York subway. Police said an unidentified man pushed 61-year-old Wai Kuen Kwok onto the tracks and into the path of an oncoming train on Sunday morning. Kwok, who had been standing on the platform with his wife, was struck by a southbound train at around 8.40am at the 167th Street and Grand Concourse station. He was pronounced dead at the scene. His wife was not injured. The assailant fled but authorities have released video footage of a man wanted in connection with the horrific incident. Witnesses said they believed the man fled the subway station after shoving Kwok and jumped on a city bus. There have been three other incidents in recent years that have involved a person being pushed onto the tracks. In April 2013, a train ran over a man desperately clawing at a Manhattan subway platform after being pushed onto the tracks by a homeless suspect with whom he'd been arguing. In December 2012, another homeless man was arrested for pushing a Queens man in front of a Times Square train that fatally crushed him. And later the same month, a mumbling woman pushed a man to his death in front of a subway train in Queens. This is not on. You don't just push people in front of a train like that. It may be a good idea for a joke at the time, but you won't find it funny when the cops get involved.
