Christchurch Police have arrested and charged a 15-year-old youth with aggravated robbery.
The action comes after the J-Mart Dairy in the suburb of Opawa was targeted on April 13.
Two males had entered the dairy and robbed the sole attendant of cash and cigarettes while armed with a tomahawk and a kitchen knife.
The youth was to appear at the Christchurch Youth Court today, and police would oppose bail.
The youth currently has an active charge for another robbery.
