Armed police have surrounded a Christchurch house this afternoon.

A witness told the Herald at least 12 police cars are surrounding a property in McLeod St, Richmond, and described police armed with guns and dog units.

The source claimed police were tossing “flash grenades” into a property and yelling for someone to come out.

Members of the public have been told to stay away but a large crowd of around 100 people has gathered to watch from outside the cordons.

Some neighbours say they heard screaming from the home last night.

It comes just hours after a person was taken into police custody after reports of an armed man outside Christchurch.

Police responded to “a reported firearms sighting” in Spencerville just north of the city after midday.
