Two men have been arrested and charged after allegedly stopping motorists and threatening them with a firearm.

Police said the charges were laid after two separate incidents where motorists were followed, forced to stop and then threatened with a firearm.

Detective Senior Sergeant Ben Bergin said the incidents happened on Saturday, April 25, in Northland and Waitematā, Auckland.

“These incidents left the victims understandably shaken and we acted swiftly to locate those we believe to be responsible.”

The alleged offenders are aged 46 and 30 from Bay of Plenty and Northland.

They are due to appear in the North Shore District Court on May 4 on charges including intentional damage, dangerous driving, possession of methamphetamine for supply, and committing an imprisonable offence with a weapon.

Police are not ruling out that there may be other victims from similar incidents on Saturday.

“We would like to hear from anyone who believes they may have been targeted in a similar way, such as being followed, forced to stop or threatened with a firearm on April 25 in the Northland or Waitematā area,” Bergin said.

Police are also working to determine whether the reports are linked to a firearm found in the Mangawhai area on April 25 and handed into police by a member of the public.

Bergin said police won’t tolerate “intimidating and violent offending”.

“If you can assist our inquiries, please get in touch with us as soon as possible.”
