BERKELEY, Missouri (PIX11) – In an unusually rapid release, police in Missouri have made public surveillance footage from a gas station where an officer shot and killed a teen he says pointed a gun at him.

It happened about 11:15 p.m. Tuesday at a Mobile station in Berkeley, Missouri, a town near Ferguson, where the shooting death of an unarmed black teen and a grand jury’s decision to not indict the officer who killed him sparked days of nationwide protests, some of them violent, and calls for reform.

The video was posted to the St. Louis County Police Department’s YouTube page about 8 hours later. A spokesman with the police department confirmed to PIX11 News that the video is official.

An officer was conducting a routine business check at the gas station when he saw two males on the side of the building and approached the pair, police said. At 1:36 into the video, one of those males raises an arm at the officer.

The 18-year-old, identified by family as Antonio Martin, held a gun “straight out” at the officer before that officer fired “what we think … were three shots,” St. Louis County Police Chief Jon Belmar said Thursday.

The man — who died after being shot by the officer — is not believed to have fired any shots himself, according to Belmar.

As news of the shooting spread, a crowd gathered, some among them yelling at a number of police officers who also had arrived. What looked like a firecracker exploded near a gas pump, video from CNN affiliate KMOV showed. A scuffle broke out, and officers grabbed some of the demonstrators and led them off in handcuffs.

Missouri state Sen. Maria Chappelle-Nadal, who has criticized authorities over the Brown shooting, appealed for calm Wednesday morning — saying that if indeed Martin was armed, she felt Tuesday’s shooting could be different.

“While tensions are high, we need to be respectful of what the facts are, and then our actions need to follow those facts,” Chappelle-Nadal told CNN’s “New Day.”

“While we’re waiting for the facts, we need to have some calm so we know that’s going on. Not every case is the same,” she said.

The second male who was with the now-deceased teen ran from the gas station, police said.

An investigation is ongoing. Police said they recovered a weapon at the scene.
