A police officer in Ferguson, Missouri, was shot Saturday night.
The shooting happened about 9:10 p.m. when a Ferguson police officer saw two men near a Ferguson-area community center, St. Louis Police Chief Jon Belmar said at a news conference. The officer, who was in a patrol car by himself at the time, got out and ended up chasing the men. During the chase, one of the men turned and fired at the office. The bullet struck the officer in the arm.
Belmar said the officer "was able to get a couple shots off," though police Saturday had "no evidence that either suspect was shot." Both men remained at large early Sunday morning. The officer was being treated for his wounds and he was expected to recover.
Neither Belmar nor police representatives who spoke with BuzzFeed News offered additional details Saturday night. Belmar added that he was unaware of any other shootings late Saturday — despite widespread rumors on social media that another person had been killed by police.
Police did not immediately provide a specific address for the incident, but video and images posted online immediately after the shooting showed crime scene tape and crowds near St. Peter's Evangelical United Church of Christ, at 1425 Stein Road.
Police do not believe the shooting was related to the protests that had been happening earlier Saturday evening.
Belmar described the scene of the shooting as "an area that's fairly secluded." He added that the shooting "certainly doesn't appear" to be connected to to the protests.
Soon after the shooting, Missouri Highway Patrol Capt. Ron Johnson briefly addressed protesters and told them to go home.
Despite police assertions that the shooting was unrelated to the protests, the incident sent tensions soaring early Sunday morning.
In the immediate aftermath of the shooting, police massed in several locations. And despite orders from Johnson and others to disperse, protesters remained out on the streets. People initially gathered at various locations, including near the scene of the shooting, but by about midnight were gathering in downtown Ferguson near police headquarters.
The unrest continued Sunday into the late evening and into the next morning.
The shooting came after a sometimes-tense evening of protests.
Earlier Saturday, a man showed up a the protest holding an "I am Darren Wilson" sign. The sign — which was meant to express support for the officer who killed unarmed teenager Michael Brown on Aug. 9 — apparently incited protesters. Witnesses at the scene later tweeted that police removed the man.
The shooting also happened two days after protesters and officers scuffled outside the police station.
A St. Louis City police officer also was injured Saturday night on Interstate 70.
Police told The Riverfront Times that a vehicle with several males inside pulled up along side the officer's car and from two lanes away opened fire. There were several bullet holes in the car, but the officer sustained only minor injuries.
The shooting happened about midnight, The St. Louis Post-Dispatch reported.
St. Louis County's police department has released a statement regarding both shootings.
