A number of deputies were wounded after being called to the scene of a domestic disturbance in a residential area south of Denver on Sunday, authorities said.

The Douglas County Sheriff’s Office said via its Twitter account that shots were fired in the course of the investigation and “multiple” deputies were injured. The shooting happened at the Copper Canyon Apartments in Highlands Ranch. The landscaped apartment complex is 28 kilometres south of Denver.

Residents in the vicinity were advised to stay inside and avoid exterior walls and windows. Police are using a local recreation centre as an emergency shelter for those seeking safety in the area. 

“During the Investigation, shots were fired and multiple deputies were injured. No status on the deputies and no status on civilian injuries. Please avoid this area,” the sheriff’s office said in a tweet.

Linda Watson, spokesperson for the Sky Ridge Medical Center, told CBC that three people in “non-critical” condition had been transported there for treatment. She did not say if the patients were police officers. 

Law enforcement agencies including the Parker Police Department, the Lone Tree Police Department, the Castle Rock Police Department and the Colorado State Patrol were assisting. Deputy Jason Blanchard, with the Douglas County sheriff’s office, told the Denver Post that a SWAT team had been called to the scene.
