A teenager has been arrested following the attempted robbery of Highgate Dairy, in Dunedin, earlier this month.
On the evening of August 8, a person allegedly wielding a knife entered the store and threatened a staff member.
When he realised someone else was in the dairy, the offender ran off empty-handed.
Police said a 15-year-old male had been charged with assault with intent to rob, and referred to Youth Aid.
