A mass shooting in Boulder, Colorado left multiple people dead, including a police officer on Monday.
That's according to authorities, who also confirmed that a suspect injured in the violence has been arrested.
Police gave no known motive for the violence, which unfolded at about 3 p.m. at a King Soopers grocery store in the Table Mesa area of Boulder, some 28 miles northwest of Denver.
Boulder Police Chief Maris Herold said 51-year-old police officer Eric Talley was killed in the shooting.
"Officer Talley responded to the scene, was the first on the scene, and he was fatally shot. I also want to commend the heroic actions of the officers responding not only from Boulder PD but from across the county and other parts of this region."
Police said the suspected gunman was believed to be the only individual with serious injuries who survived the bloodshed.
Video footage from a CBS affiliate at the scene showed a shirtless, bearded man in boxer shorts being led away from the store in handcuffs, before he was placed on a stretcher and loaded into an ambulance.
The man in custody appeared to have a bloody leg and was limping as he walked.
Monday's bloodshed marks the second mass shooting in a week, following a deadly rampage in Atlanta last Tuesday that left eight people dead, predominantly Asian women.
