Man, 34, killed at Bronx station in afternoon shooting police say was prompted by argument between two teen groups

An argument between two groups of teenagers left one person killed and five others injured in a shooting at a New York subway station on Monday, police said.

The shooting started after the train's doors opened on the elevated platform at the Mount Eden Avenue station in The Bronx at about 4.38pm - a time when stations throughout the city are filled with kids returning from school and when many workers are beginning their evening commute.
