Screams and police dogs' barks were heard from within a Christchurch property as armed officers arrested a man during a three-hour stand-off.
It comes as a homicide investigation has been launched after a teenager's death late Friday night.
Police have been at a Dunster St address since 4:50 pm today.
Two police dogs were recently seen leaving the property shortly before a man was led into a vehicle in handcuffs.
