Christchurch Police are investigating a home invasion in the suburb of Redwood - during which a woman was injured and a loaded shotgun was pointed at police.
Police were called to a house in Northcote Road just after 1am this morning by a neighbour.
It's understood two men both wearing balaclavas forced their way into the house, where a mum and two young children had been asleep and demanded money.
When officers arrived, the offenders fled and presented a loaded shotgun at officers when they tracked him down in a nearby street.
Detective Sergeant Chris Power says the woman was injured after leaving the house through a broken glass door and the children were safely removed by police and family members.
James Carpenter appeared in the Christchurch District Court this morning on firearms and aggravated robbery charges and has been remanded in custody until the 11th.
The Police Commissioner is praising the actions of the two Christchurch police officers and police dog after they disarmed the shotgun wielding man.
Peter Marshall says Constable Lyal Bayliss and police dog Brock showed remarkable courage by disarming the offender.
He says having a loaded weapon pointed at you is terrifying and to react in such a manner was a very brave thing to do.
Police are still looking for two others.
