Three police officers were shot in Bristol, Connecticut Wednesday night, according to state police. Connecticut State Police were responding to an officer-involved shooting in the Redstone Hill Road area, local station WFSB reported.

"The Connecticut State Police [Public Information Office] is on scene at the Bristol officer involved shooting. There were injuries reported," police said in a news release early Thursday.

Residents heard between 20 and 30 gunshots as officers were seen surrounding a house, according to Eliza Kruczynski, a reporter with local news station station WFSB.

The extent of the officers' injuries was not immediately known. No information about a suspect or suspects and the circumstances that led to the shooting was released.

State police told the station that three officers were struck by bullets. They didn’t provide details on the extent of the cops’ injuries.

It was not immediately clear what police agency the officers who were shot worked with. Bristol police and state troopers were at the scene.

A nearby resident told NBC Connecticut that he heard at least a dozen gunshots followed by a 30-second pause and then another dozen gunshots.

“It’s scary, especially Bristol is a peaceful town and it’s scary to hear something like this is happening here,” resident Ted Krawiec told the station.
