HOUSTON (AP) - A man was shot and killed in a southeast Houston apartment as he attempted to flee gunmen trying to kick down the door.

Houston police said the man, whose name was not released, was visiting a friend when several unknown men came to the apartment door around 2:10 a.m. Thursday and attempted to force their way in.

When their efforts to kick down the door failed, police said the assailants began shooting through it.

The man attempted to escape by jumping through a second floor window when he was struck by gunfire.

Police said he died at the scene and those chasing him left without entering the apartment.

A motive is not yet known. Police say they continue to investigate.
