Authorities say a Chicago police officer shot and killed a 16-year-old in the city’s North Lawndale neighborhood during a foot chase Thursday night. We report from our West Side bureau.

A police statement says officers on South Spaulding Avenue spotted three males fleeing across a vacant lot around 9:15 p.m. The statement says one of the suspects, identified later as Rakeem Nance, was wearing a mask and carrying a gun.

A Chicago Public Schools spokesman says Nance was a ninth-grader at Collins Academy High School.

The police say one of the officers fired on the boy after he pointed the gun at other cops who’d arrived on the scene. The other two suspects got away, and none of the officers sustained injuries.

A Mount Sinai Hospital spokeswoman says Nance died about two hours later in the operating room.

The police say an investigation revealed a nearby home invasion moments before the shooting.

An office that investigates police conduct for Mayor Richard Daley is looking into the shooting.
