Gang member who allegedly kidnapped, assaulted woman numerous times hands himself in

A gang member who was wanted by police for allegedly kidnapping and assaulting a woman has handed himself in. 

The 33-year-old man turned himself in at Henderson Police Station overnight and will appear in the Waitākere District Court on Tuesday.  

"Police thank the wider community for sharing our appeal as part of this investigation," a police spokesperson said.

"The investigation into the incident remains ongoing, and we cannot rule out further charges being laid."

On Monday, Detective Senior Sergeant Nick Poland of Waitematā said the woman was kidnapped by a group of offenders from a house in the Auckland suburb of Birkenhead on June 12. A missing person's report was filed on June 27.

"We believe she was then transported to an address in west Auckland where she has been subjected to numerous assaults, before being taken to Northland," Poland said.

Police conducted several search warrants across Waitematā and Northland last week as they continued to search for the missing woman.

Last Thursday, she managed to escape from a vehicle parked in Tikipunga, Whangārei and sought help from a nearby ambulance.

The woman received medical attention for injuries, which were not life-threatening. Police said she was subjected to a "horrific ordeal".

Police conducted further search warrants at two properties in Whangārei last Thursday and a scene examination found a gun at one of the houses.

Poland acknowledged the kidnapping is "confronting" and said people will "understandably be feeling concerned by what has occurred". He said police don't believe it was a random attack.

"Support is in place for the victim however we must stress the importance of her safety - and as such we are not in a position to release further details around her identity at this stage."
