Two teens have been arrested and charged over the armed robbery of a Christchurch dairy and a subsequent car chase.
The 16-year-old males face a number of charges following Saturday night's events.
Police say three people entered the dairy on Division St late in the afternoon, armed with a baseball bat and a firearm, and stole cash and cigarettes.
They were later found in a stolen vehicle, where the driver failed to stop for police.
The two were arrested when the car chase ended about 10:20pm, about 11km away in Avondale Rd.
The charged pair will appear in Christchurch District Court on Monday and police are trying to find the third person.
