A man has been arrested after armed thieves disguised as police officers robbed students in Birkenhead, Auckland, last month.

A 32-year-old man appeared over the weekend on charges of aggravated assault, kidnapping, committing a burglary with a weapon, and impersonating police.

Just after midnight on April 13, two men allegedly entered an address in Birkenhead, wearing what appeared to be high visibility police vests.

One of the students told the Herald he returned home to find his flat turned upside down and his two flatmates fearing for their lives after a confrontation with the fake cops, who threatened them and stole a number of items.

A police spokesperson said a man has been arrested after searching a Manurewa property.

He is due to reappear in the North Shore District Court tomorrow.

Waitematā East Area investigations manager, Detective Senior Sergeant Nick Poland said inquiries are ongoing to find the uniform reportedly used and confirm if it is a legitimate New Zealand police uniform.

“In general, Police staff will be clearly identifiable in uniform and will be carrying police identification that can be presented upon request. We advise anyone who is dealing with a representative or agency to question their identification if they are unsure.”
