Two teens have been charged after a botched ram raid in Whanganui this morning saw a vehicle roll down a hill into a tanker.

The 14-year-old and 16-year-old allegedly fled the scene with "a small amount of chocolate," police said.

Police received reports about a stolen vehicle about 5am, shortly before alarms went off at a BP station on Taupo Quay.

Upon arrival at the petrol station two minutes later, police found the stolen vehicle with significant damage.


The BP station's shop front was also damaged.

"It appears two people have attempted to ram raid the shop. However, after ramming the shop, the car has rolled down a slope colliding with a bowser," police said.

CCTV footage provided a description of the alleged offenders and police searching the area found them nearby, about half an hour later.

A 14-year-old and a 16-year-old will be charged with burglary and unlawfully taking a motor vehicle and will be dealt with by Youth Aid.
