Colorado Springs police arrested two people early Sunday on suspicion of aggravated robbery and one on suspicion of obstructing a police officer after an altercation at a nightclub escalated to gunfire in the parking lot.

Officers were dispatched to the 3700 block of Astrozon Boulevard at 2:15 a.m. when an altercation inside the club carried over to the parking lot, according to an online blotter post. 

“At least” two suspects, later identified as Karriem Johnson and Lugene Burnett, allegedly assaulted a man and stole his firearm. Gunshots were also reported, the blotter post states. 

While officers were investigating the scene, Johnson and Burnett allegedly returned to the parking lot, leading to their arrest, according to the blotter post. The two men face charges of assault and aggravated robbery.

During their arrest, a bystander approached the patrol vehicle and began interfering with Johnson and Burnett’s arrests. The bystander was arrested on a charge of obstructing a peace officer.
