Two teenagers have been arrested after allegedly setting fire to an ice cream shop in Melbourne.

Emergency crews were called out to a fire at the shop on Wool St, Tarneit, about 2.30am on Saturday.

Fire fighters managed to bring the blaze under control, however, the shop was significantly damaged.

CCTV of the alleged incident shows two hooded figures ram a car into the shop front, before taking out a petrol can and entering the building.

A fire and an explosion can be seen before the two figures return to the car and drive away.

Investigators located a Toyota Landcruiser, believed to be involved in the incident, dumped at the intersection of Dohertys and Mount Cottrell Rd in Mount Cottrell.

Police, dog squad and Air Wing searched the area before two 17-year-old boys from the Greater Dandenong area were found and taken into custody about 5am.

One of the boys was taken to hospital after being bitten by a police dog.

Shop owner Mahmood said he had no answers as to why his shop was targeted.

“I need to ask the one who burnt my shop why he’s done (it). Why? what have I done to you?” he said.

“I checked the cameras, (there were) one or two people with a big bottle of petrol, they put petrol (inside the shop) and they burnt it.”

Another family member called the incident “shocking”.

“It’s very shocking, we don’t have any problems with anyone,” they said.

A crime scene has been established, and an arson chemist is expected to attend, police said.

The investigation is ongoing.

Anyone who witnessed the incident, has dashcam or CCTV footage or anyone with information is urged to contact Crime Stoppers.
