Detective Inspector Scott Beard, of Auckland, said the teen has been charged with assault with intent to rob and aggravated wounding. He's been remanded in Oranga Tamariki care until July 16.

A mother and her adult son are recovering from surgery after being stabbed at the Hylite Dairy on Great North Rd.
