Armed police descended on a residential area of West Auckland this afternoon after a man threatened another with a gun.

Police have arrested one person and confiscated their slug gun.

Video of the incident shows an armed officer shuffling a worried woman and young child into a bus shelter. Other armed officers can be seen taking up positions behind a truck and a fence at the end of a driveway.

Earlier, a witness told the Herald she saw at least six police cars outside the West Harbour Fire Station just before 1pm.

“One female cop jumped in the front with her gun slung over her shoulder,” the witness said.

“Cops all armed and jumped in the cars carrying their guns before taking off and going into Oriel Ave.”

A police spokesperson said police were armed as a precaution.
