Christchurch police have charged nine men following an assault and kidnapping complaint.
The Armed Offenders Squad was called out to secure a property in Bowenvale Ave in Cashmere and another property in Ajax Street in Shirley this morning.
The police carried out search warrants at the homes and forensic examinations are being carried out.
Detective Senior Sergeant Anderson said nine men had been charged with wounding with intent to cause grievous bodily harm and kidnapping.
"There is still a large amount of investigation work to be done and there are other people the police want to speak with."
"All the people involved are known to each other and there are no immediate concerns for the wider public."
The nine men will appear in the Christchurch District Court tomorrow.
