THE life of a teenage girl was put at risk when the tyres of an ambulance were slashed outside a party at Warriewood on Friday night.

Paramedics believed the girl was suffering adverse effects of consuming drugs or alcohol and needed hospital treatment.

But when they returned to their ambulance, the paramedics found three tyres of their vehicle had been slashed and they had to call for a second ambulance to take to the girl to hospital.

Northern Beaches crime manager Insp Craig Wonders said paramedics were called to a house in Alameda Way at Warriewood at 11.30pm on Friday following reports that a teenage girl needed treatment.

After assessing the girl, the paramedics took her to their ambulance, where they saw that three of its tyres had been punctured, rendering the vehicle unusable.

A second ambulance was called, as were the police.

After the girl was taken to hospital by the second ambulance, the police began questioning other partygoers at the address, some of whom Insp Wonder said appeared to be under the influence of drugs or alcohol.

He said they were all in their late teens or early 20s.

“The police are trying to identify those responsible for the damage to the ambulance,” he said.

“We’re treating this as a very serious offence due to fact that an ambulance crew called to render medical assistance was taken out of action and a further ambulance had to be called in.

“The consequence could have been diabolic if the medical situation had worsened or had been life-threatening for the girl.”

Insp Wonders said anyone with information about the damage to the ambulance should call Dee Why police station on 9971 3399 or Crime Stoppers anonymously on 1800 333 000.
