Explosions were heard near the Port Alberni Fire Hall Sunday morning, and police say the fire is suspicious, and under investigation.
A 5th-wheel trailer, three vehicles and a detached garage were destroyed by the fire in the 3500 block of 10th Avenue.
Acting Fire Chief Wes Patterson said the quick response from firefighters kept the fire from spreading to neighbouring houses, but there was some damage to properties on both sides of the blaze.
No one was injured despite multiple explosions of gas tanks, propane tanks and tires.
