Windsor firefighters were busy on the weekend.

Five vehicles were set on fire in a car lot in the 6500 block of Tecumseh Road East.

Damage is estimated at $80,000. Arson is said to be the cause.

It's the second time since August vehicles have been set on fire in the same lot, said Lee tome, the city's chief fire prevention officer.

A second fire on the city's east side early Saturday is also suspicious. It was in a vacant building on Drouillard Road. the building once housed Adler's Bakery.

"The crew set up defensively. They did not go in the building, because of the large amount of fire in the building," Tome said. "Within a half hour of arrival, the fire was going through the roof. We were able to protect the buildings around it. Fortunately, they weren't very close."

A demolition team had to be called in to tear down the remains of the structure.
