VIDEO: House explodes on live TV

Fire breaks out after gunfire kills police officer

A house in New Hampshire exploded live on air after a fire broke out, following gunfire at the property.

Two police officers were responding to a report of a domestic dispute between the owner of the house and his son when gunshots were fired.

One of the police officers, Stephen Arkell, 48, was killed and the second officer was driven out. The shooter, named as Michael Nolan, 47, is believed to have started the fire which led to the explosion. The house was completely destroyed

Investigators believe Nolan was killed in the fire. His father, Walter Nolan, 87, was taken to hospital for minor injuries.

The Governor of New Hampshire, Maggie Hassan, ordered that flags be flown at half-mast in Arkell's honor.

"Officer Arkell bravely answered the call of duty and made the ultimate sacrifice, a heroic demonstration of his commitment to the safety of his fellow citizens. Like so many of our first responders do on a daily basis, Officer Arkell courageously put his life on the line to protect others, and in doing so, was tragically taken far too soon."
