Three teenagers have been arrested after a series of incidents, including an aggravated robbery, in Auckland.
Police said a group of people were walking home on West Coast Road in Glen Eden last Tuesday night when they were approached by a group of youths, who allegedly threatened them.
The teenagers are accused of kicking and punching the four people and taking one of their bags.
Police said the group were also involved in a fight on a train earlier that night and another dispute in the area.
Officers arrested the teenagers, aged between 15 and 18, yesterday.
Two face aggravated robbery charges - the third has been referred to Youth Aid.
