Two Darwin service stations were robbed overnight, with five males arrested, and a large group of females still on the run, NT Police said.

Police director of communications Mark Wilton said that between 8:30pm and 11:00pm on Wednesday, Strike force Trident responded to two service station robberies along Trower Road in Casuarina.

“The first service station was entered by a group of female youths that threatened the employee before stealing a quantity of cigarettes and fleeing the scene,” he said.

“The second service station was unlawfully entered by a group of male youths and adults who gained access by damaging the entry doors. The group stole a quantity of small items before fleeing.”

Mr Wilton said there had been three boys and two men arrested and they remain in custody, while police expected further arrests.
