The St. Louis County Police Department confirmed Friday that federal law enforcement officials fired shots and arrested two men outside an apartment complex in Ferguson, Missouri, the community rocked by the fatal police shooting of unarmed teen Michael Brown in August.

Witnesses say the Federal Bureau of Alcohol Tobacco and Firearms (ATF) fired into a black Chevy parked on the grass near the Park Ridge apartments at the intersection of Ferguson Road and Sharondale.

According to a Fox news report, the occupants of the car were two black males. One was taken away in an ambulance with a gunshot wound to his leg and the other was taken in the back of a police car.

“It happened right out in front of my house,” said witness and Ferguson resident Robernae Perry. “We saw the police taking pictures of the black car in the morning and then they left -- but I don’t think they left; I think they were hiding out.”

A few hours later Perry heard shots being fired and rushed to her window to see the ATF apprehending the men in the car. “They stomped on the head of the guy that wasn’t shot,” alleged Perry.

More details will be posted as the story develops.
