Ten people have been arrested after a man was stabbed to death in Blenheim early on Sunday morning.
Emergency services were called to the incident on Market Pl at about 2:55am where one person died at the scene. Two others were seriously injured and taken to hospital where they remain in a serious condition.
Police say they have now arrested 10 people. They have been charged with a range of charges including murder, wounding with intent to cause grievous bodily harm, assault and disorderly behaviour.
