Witnesses who watched an armed police stop unfold on Cambridge Road describe the event as "crazy".

One of the witnesses says two police cars stopped a red car on Cambridge Road after following the vehicle for a while.

"Police had closed down Cambridge Road as they took someone into custody just before 8pm.

"It was an armed stop. They had followed the car from the Mount.

"I saw them as I was directly behind the police cars. They all turned their lights on and pulled the car over about 20m from Te Atatu Place.

"One of the police units parked in the middle of the road and didn't allow us past for five minutes.

"I saw police with guns pointed at the vehicle and the officers were yelling commands at the driver."

The witness says police then took the driver into custody and re-opened the road.

Another witness described the event as "completely crazy".

A police spokesperson says all the information they have at this stage is that a "routine traffic stop was conducted on Cambridge Road in the last hour".
