Four people were taken into custody following a report of a shooting in Loveland on Thursday evening.

Loveland police received a call at 6:25 p.m. from someone at the Unity Club, 102 E. Third St., according to Lt. Jan Burreson.

"They were having a meeting, and they heard a loud bang above them," Burreson said.

On top of the meeting space, which is housed in a converted two-story home, is an apartment. Following the bang, Burreson said, a hole came through the ceiling. No injuries were reported.

The Unity Club members evacuated before calling police, and when officers arrived and called into the upstairs apartment, several people exited it.

Aims Community College's Loveland campus sent a message to its students about an active shooter in the area and put the campus on lockdown. According to Laura Coale, Aims executive director of communications and public information, someone noticed the activity in the area and alerted the on-duty security guard who initiated the request for the message.

Coale said the lockdown only lasted a few minutes as Loveland police responded to the incident.

Police responded within a couple of minutes of the initial call and set up a secured perimeter around the area. Detectives conducted a search warrant on the building where they located what they believe was a shotgun blast on the floor.

According to Burreson, police are still investigating who fired the shot and whether it was accidental, but there is no threat to the public.

Officers recovered the sawed-off shotgun that was used, which Burreson said had its barrel cut to an illegal length.

The individuals arrested were taken into custody based on unrelated outstanding felony warrants, and no charges have yet been filed for the shooting. Their names have not yet been released.
