Three men, including one with a weapon, forced their way into a Christchurch home, locked a man in a cupboard, and stole thousands of dollars' worth of electronic gear.
Police say the victim may know at least one of the offenders who burst into his Bishopdale home around 9.15pm last night.
The victim was confronted at his front door by three men, one of whom was armed with a weapon, Detective Sergeant Hamish Wilson said.
After an altercation, the three assailants tried to restrain the man using duct tape.
"This was not successful and the victim was held down on the ground before being shut in a cupboard in another part of the house," Mr Wilson said.
