A 13-year-old boy, who was part of a group that allegedly robbed a Katherine service station and threatened a staff member, has been charged, NT Police said.

Superintendent Craig Garland said in the early hours of November 28, the group of youths allegedly approached and threatened an employee, demanding cigarettes and cash in an unnamed service station in Katherine.

It was not detailed if the staff member had sustained any injuries.

The boy has been charged with attempted robbery, going armed in public, and making threats to kill a person. He will face court on an undisclosed date.

“It is very concerning that a 13-year-old has been involved in such serious offences,” Supt Garland said in a statement.

“But we are pleased to say that police are working with the family and other community groups to reduce the likelihood of his reoffending.”

It was not explained specifically what role youth diversion measures would play in this case.

Police said investigations are continuing to locate the other youths involved in the incident.
