(CNN) — A powerful explosion tore through a duplex in Brentwood, New Hampshire, Monday afternoon, after a man shot and killed a police officer who responded to a domestic dispute there, authorities said.
The blast was captured live on air by CNN affiliate WCVB-TV.
Officer Steve Arkell was fatally shot by Michael Nolan, 47, according to New Hampshire Attorney General Joseph Foster. A second officer responded to the scene but was driven away by gunfire, Foster said.
“Other officers arrived and a short time later the home was engulfed in flames and later exploded,” he said. “It’s believed Mr. Nolan was killed by the fire or the explosion.”
