MONTREAL - Three people have been arrested in connection with a blaze that destroyed a Hells Angels bunker last week in Quebec.

Quebec provincial police say the suspects face charges of car theft, conspiracy to commit arson and arson.

Police say two men were seen leaving the area in a pickup just after a tanker truck, which had been reported stolen, smashed into the fortified building and exploded.

Provincial police say they have not yet linked the fires to organized crime.

Police say three fires were set at different buildings in the city of Sorel-Tracy over a span of a few hours.

Some police and observers of the biker scene have expressed fears that the attack could be a sign of a renewed biker war in Quebec.

The fire followed the recent seizure of large quantities of explosives and the arrests of three men linked to bikers.
