Four teens have been charged after allegedly going on an early morning crime spree, targeting service stations around Adelaide.
At about 3am on Saturday, SA Police were called to a service station on Glen Osmond road in Glenunga, about 5 km from the Adelaide CBD, after four teenagers had approached the doors with their faces covered.
Staff inside immediately locked the doors to stop the teens, who then fled empty-handed.
But about 50 minutes later, police were called to a service station in nearby Glenside after reports three armed teens had threatened staff and stolen cash and cigarettes.
They were last seen getting into a blue Lexus and driving away.
At about 4.40am, police again received reports of three armed teenagers entering a service station in the northern suburb of Angle Vale and threatening staff.
Workers at the service station refused to hand over any cash, and the teens fled empty-handed.
Just before 5.30am, three armed teens threatened staff at another service station in Croydon, but again left empty-handed.
Half an hour later, police attended a home in Ferryden Park after reports four teens had been acting suspiciously.
Patrols, along with two police dogs quickly located and arrested three teens, and a fourth was found hiding in a backyard.
The blue Lexus was also located, and police checks revealed it had been stolen sometime overnight.
A 14-year-old Ferryden Park boy and 15-year-old Andrews Farm boy are expected to be charged with aggravated robbery, carrying an offensive weapon and illegal use of a motor vehicle.
A 14-year-old Brompton boy and a 13-year-old Clovelly Park boy are expected to be charged with aggravated robbery, attempted aggravated robbery, illegal use of a motor vehicle and other charges related to a separate incident on April 16.
All four teens have been refused police bail and will face the Adelaide Youth Court on Monday.
