BLOOMINGTON - Police were looking Thursday for two men they think shot at a passing vehicle, reports of which prompted police to surround an apartment with guns drawn for three hours Wednesday.

The men are wanted on warrants and their names aren't yet being released, said Bloomington police spokesman Duane Moss. Nobody was injured when an orange Chevrolet Suburban was shot at about 11:40 a.m. Wednesday in the 1400 block of West Market Street, police said.

Witnesses told police the gunmen fled to a nearby apartment building, and several dozen officers surrounded it. Police cleared nearby buildings and parking lots and redirected traffic at nearby intersections until about 2:45 p.m.

Officers with the Emergency Response Unit, the city's tactical unit, found no one in the apartment when they went inside about 2:30 p.m., Moss said Wednesday. A woman and two children were removed from the apartment an hour earlier, he said.

Police initially said one man shot at the sport utility vehicle as it headed north on Holton Street toward Market Street, but Moss said a police report now indicates both men fired at the vehicle. He did not know if the two wanted men lived in the apartment building the men reportedly fled to.

Police later found the SUV and four occupants - three men and a woman - at a North Main Street convenience store, Moss said. A rear driver's side window was broken out, Moss said, but he didn't know how many times the vehicle was struck by bullets.

Moss declined to give specifics when asked how well administrators thought the incident was handled. But he said any such emergency can be used and evaluated to improve the department's responses.

"We'll learn from it and perhaps make changes if similar situations come up," Moss said.

Moss declined to say how police tried to determine how many people were in the home or whether the suspects were there.

"The crisis negotiation unit has specific ways they do things, and a lot of those things we wouldn't talk about publicly," Moss said.
