Police are hunting for vandals who slashed tyres of three ambulances, forcing them off the road in an attack described as “irresponsible”.

Counties Manukau Police are investigating the damage caused by the offenders after they broke into the gated yard of St John’s Manukau Station on Saturday night and punctured five tyres of three vehicles.

The station sits on the corner of Plunket Ave and Wiri Station Rd.

Senior Sergeant Roelof Burger said the vehicles will now be yard-bound for a “period of time”.

“While in the yard the offenders have punctured five tyres on three vehicles using a sharp object, rendering them inoperable.”

Burger described the actions as “destructive” and warned it can put people’s lives at risk.

“As the vehicles are inoperable for a period of time, this impacts St John’s ability to respond to those who are in need of medical attention within our community.”

Hato Hone St John district operations manager Andy Everiss said he was disappointed by the “unwarranted attack”.

“These ambulance vehicles are a vital part of how we continue to support and serve the local community.

“These actions show great disrespect to our people, who rely on these vehicles to do lifesaving work every day.”

Everiss confirmed the incident has not impacted emergency ambulance response and St John remains available in an emergency.

Police enquiries to identify and locate the offenders is ongoing and anyone with information is being asked to contact police by calling 105 using the reference number P065611930.

“We would also like to hear from anyone with CCTV or dashcam footage in the wider Plunket Avenue and Wiri Station Road areas,” said Burger.
