Police are on the hunt for two firebugs who set fire to a northern suburbs lolly store.

Emergency services were called to a blaze at Candy Station — an American-style grocery store — at the Ballajura City Shopping Centre about 3.40am on Tuesday.

The fire caused damage to the front and interior of the building.

Arson Squad investigators examined the scene and determined the blaze was deliberately lit.

Police footage shows two masked men approach the store carrying a petrol canister and a large axe.

One man can be seen attempting to break into the store by destroying the front lock with the axe.

Anyone with any information relating to this incident is urged to contact Crime Stoppers on 1800 333 000 or make a report online here.

Rewards of up to $25,000 are available for information that leads to the identification and conviction of an arsonist.
