Four teenagers were arrested after allegedly brandishing a fake gun in a Dunedin department store on Saturday following a 360km joyride from Christchurch using two stolen cars.

One of the group, a 14-year-old, allegedly stole a Mazda Demio from an address in Christchurch, recently named one of New Zealand’s most stolen cars.

The teen and a 16-year-old passenger drove the stolen vehicle to Temuka where they picked up another 14-year-old and continued south, a police spokesperson said.

The trio later dumped the car in Oamuru and allegedly stole another vehicle before driving to Dunedin.

Police were then called to Farmers George St in central Dunedin after the four youths were allegedly seen pointing an imitation firearm at staff and customers.

“Police located the group walking along St Andrew St, and one of the boys handed over a BB gun,” said a spokesperson.

A 15-year-old was returned to caregivers while the 14-year-old was charged on two counts of unlawfully taking a motor vehicle.

The other 14-year-old and the 16-year-old were both charged with two charges of unlawfully getting into stolen motor vehicles, with the older boy also charged with wilful damage.
