An 18-year-old has admitted being the decoy who defeated door security measures to allow the robbery of the Woolston Night n Day store in the early hours of March 8.
Dominic Pomama, of Woolston, admitted the robbery charge before Judge Raoul Neave in the Christchurch District Court today, and was remanded in custody for sentencing on October 18.
The judge gave him a first-strike warning under the system that imposes heavier penalties on repeat violent offenders.
Pomama’s two co-offenders, who were masked during the robbery, have never been identified. They are referred to in the joint charge as being “persons unknown”.
Pomama was originally charged with robbery using a metal bar as a weapon, but the Crown later accepted that they could not prove that he knew the weapon was being carried by one of the unknown offenders.
He has been in custody since his arrest soon after the robbery.
Crown prosecutor Barnaby Hawes said Pomama and the others decided to rob the dairy on Ferry Road and parked their vehicle close to the dairy.
Pomama went to the dairy while the other two “positioned themselves” out of sight.
He knocked on the door and was let in through a door which opened with a switch operated by the shop assistant.
He then looked around, asked the price of drinks, and left without buying anything.
As the shop assistant operated the switch for Pomama to leave, the other two ran up and came in before the door closed behind him. One of them was carrying a dumbbell bar and the other had a bag.
Pomama walked across the car park, turned to look at the other robbers, and went to the area where the car was parked.
The robber armed with the bar yelled at the shop assistant to open the till, which he did. The one with the bag took money from the till and packets of cigarettes and they ran out and went to Pomama and the car and drove off.
It is estimated the robbers took $280 and eight packets of cigarettes.
The victim was not injuried.
Pomama told police he did not know the dairy was going to be robbed until the other two ran past him on the way in. He received five cigarettes from them afterwards.
