Chicago police overnight shot and killed an unidentified armed man who shot at police and then barricaded himself in a gangway on the South Side, police said.
The gunman hit one officer's shoe and the bulletproof vest of another, but wounded neither one, police said. He also opened fire with his semi-automatic gun on a police helicopter hovering over the scene in the Auburn Gresham community, police said.
The incident marked the second time in less than 24 hours that Chicago police responded to a barricade situation.
Police approached the man, whom they thought appeared suspicious, at West 79th and South Justine Streets about 10:30 p.m. Tuesday. As the officers approached, the man opened fire, striking an officer's shoe, police said.
