A Melbourne petrol station has been targeted in a bizarre act of sabotage. 

Vandals damaged every pump nozzle with expanding foam, costing the business thousands of dollars. 

CCTV footage captured two hooded thugs making a beeline for the petrol pumps at the BP in Williamstown.

The pair were seen filming their antics on their own camera.  

“It’s clear they knew what they were doing, it’s clear it was intentional and it’s clear it was calculated,” BP Williamstown manager James Ibrahim said. 

The pair could be seen moving quickly and methodically, spraying the substance inside every nozzle.

To avoid being spotted by potential witnesses, they then hid behind the bowser. 

A few minutes later they fled on foot.  

Staff made the discovery when they arrived a few hours later, with the station’s manager left dumbfounded. 

“It’s a bit disheartening, because look, we’ve been part of this community for almost 20 years,” Ibrahim said.

“We work to keep our prices fair and keep the competition honest as well, it’s sad that something like this would happen.”

The petrol station was closed for about five hours while each nozzle was either cleaned or replaced, costing the business about $15,000 in damages and loss of trade. 

“We have police involved, and we have some private investigators involved, and I just wanted to speak to the community,” Ibrahim said.

“If you guys have seen anything, have CCTV footage, please come forward and help us out.

“This is our home, we’re part of the community, we’re not going anywhere and we’re going to keep pumping.”
