Overnight incident in Christchurch: Resident says he heard a gunshot

A Christchurch resident says he heard a gunshot after armed police stormed his suburban street.

Jeffrey Chisholm said he woke to a helicopter flying low over his Poulton Ave home about 3.30am.

He went outside to find his front fence had been broken and armed police running down the road.

"About quarter of an hour later I got a phone call from the police telling me not to go outside, that was about half-past four.

"Then I heard a shot about quarter to five then I had another phone call atv five o'clock saying you're allowed to go outside if you want to, you're all clear."

Shirley Boys' High School principal John Laurenson also said part of North Parade was cordoned off when he walked to work along Marshland Road early this morning.

"Wandered out to the quad and happily waved at them when they shined the searchlight on me, and thought 'oh this is quite exciting for an old feller like me'."

It was unnerving having a searchlight shone on him, he said, but he didn't think much of it.

He said he had since heard from police that the incident had been resolved.

"It's all cleared now, the police have been in and said that - I'm reading between the lines - [it was] a domestic incident.

"It's open for business, or we are open for business, now."

Christchurch Transportation Centre says North Parade was closed for a time overnight but had since reopened.

Police made no comment.
