BROOMFIELD, Colo. (CBS4) – Several police officers and firefighters responded to a Walmart in Broomfield on Tuesday afternoon. Broomfield officials say police are responding to an active shooter situation.

Police arrested a woman moments after the shooting. A man was arrested later, police say.

Investigators say the two suspects knew each other and shot at each other inside the store. The shooting does not appear to be random, police say.

The store is located on 120th Avenue and Vrain Street. The scene has cleared, but the store will not reopen until 6 a.m.

Officers blocked off at least one entrance to the store and were also seen behind the building and on the roof.

Officers were seen arresting someone on the perimeter of the store. There was a stroller with a baby car seat nearby.

It is unclear whether there was a child, and whether they were harmed. Police say the stroller was not apart of the shooting investigation.

Several people were seen standing to one side of the building and in section of the parking lot.

Police say they are interviewing witnesses and employees.

Police say there are no injuries, and there is no danger to the public.
