Four people will appear in court on Monday following a series of aggravated robberies in south Auckland.
Police say an attempt was made by two teenagers to rob a liquor store in Manukau with a BB gun on Saturday night. An employee was hit over the head with the gun.
Two men were threatened on Cavendish Drive a short time later, for money and cigarettes.
But the men called police and two teenagers were arrested.
In another incident, two other men were arrested after a firearm was pulled on party-goers who would not give them money.
