<strong>At least five people were killed and 18 others injured in a mass shooting at a nightclub Saturday in Colorado Springs, Colorado, according to police.</strong>

Authorities received numerous 911 calls beginning at 11:57 p.m. and responded to the scene at the Q Club, Colorado Springs Police Lt. Pamela Castro said.

“They located an individual inside who we believe is the suspect,” Castro said. “At this time, the suspect is being treated, but he is in custody.”

In a statement on social media, Club Q said it was “devastated by the senseless attack on our community” and appreciated “the quick reactions of the heroic customers who subdued the attacker and ended this hate attack.”

Police did not release details of how the shooting ended, but Castro said “it was not an officer-involved shooting.”

The location of the shooting is reminiscent of the 2016 attack on an LGBTQ nightclub in Orlando, Florida, in which a gunman who pledged allegiance to the Islamic State killed 49 people and wounded at least 53.

Colorado has been the scene of some of the most egregious mass shootings in American history, including the 1999 Columbine High School shooting and the 2012 movie theater shooting in Aurora.

Police declined to discuss a possible motive in this latest shooting.

Colorado Governor Jared Polis (D), the country’s first openly gay governor, reacted to the shooting by calling it “disgusting.”

“This is horrible, disgusting and devastating. My heart breaks for the family and friends of the people lost, injured and traumatized in this horrific shooting,” Polis said in a statement, according to his office.
