A teenage boy disrupted an armed man early this morning who had set fire to a couch in his Canterbury home.
Southern police communications shift inspector Murray Hurst said police were called to an incident at a house in Fairlie just after 6am.
He said a 14-year-boy had disturbed an armed intruder who was setting fire to a couch inside the boy's Opihi Gorge Road home.
"He has apparently disturbed a male in the lounge of the address who has set fire to the sofa.
"The male was armed with a fire arm, didn't say anything to the young guy, and has then run off into the fog. It is a little bit unusual to say the least."
