At least eight tactical officers were injured in an explosion in North Haven, Connecticut, on Wednesday while responding to reports of a man holding his family hostage, according to a local official.
North Haven deputy police chief Jonathan R. Mulhern said "at this point in time none of the injuries are life threatening."
When the officers arrived on scene, the suspect refused to speak to them and barricaded himself inside the home, according to local media, citing Connecticut State Police Sgt. Marc Gelvin.
Police said they were not aware of any hostages, he added.
The explosion in the barn occurred as the South Central Regional SWAT team was working to to clear the outside of the home.
It was not immediately clear what caused the explosion.
