Toronto police believe an arsonist is behind a series of late-night dumpster fires, the latest in a string of suspected arsons around the city this summer.

Officers were called to Liberty Village at about 10:30 p.m. in response to a dumpster fire on Atlantic Avenue, southeast of King and Dufferin Streets.

Within half-an-hour, two additional dumpster fires were reported in the area. Eight more fires were called in over the next two hours, bringing the total to 11 by 12:30 a.m., police said.

The blazes, set in dumpsters and a portable toilet, are being treated as arson.

While no one was hurt and property damage was minimal, police say the fires could easily escalate.

"What we're concerned about is if this sort of thing were to happen again, that we might end up with more serious property damage and some injuries," Det. Sgt. John Matthews told CTV News on Tuesday.

Warehouse owner Frank Dominelli could only sift through the charred remnants of his shed on Tuesday.

"When I came here, the election signs were all burned," Dominelli told CTV News.

"There were eleven fires in a few blocks here, and thank God nobody got hurt."

Police have released the description of a suspect. He is described as between 25 and 35 years old, with curly hair, and was wearing a white T-shirt and carrying a black backpack. The suspect was riding a large mountain bike.

Anyone with information is asked to contact police at 416-808-1404, Crime Stoppers anonymously at 416-222-TIPS (8477), or go online at www.222tips.com.

Monday's fires are similar to other suspected arsons this summer that have occurred across the city.

Two vehicles and a garage were set ablaze in the Bloor West Village area on July 17 and a number of Cabbagetown homes were destroyed by fire on July 10.

Numerous fires were set in the Christie Pitts area on July 2 and a separate fire only days later gutted a million-dollar mansion.

Investigators are looking for a common link between the arsons.

No suspects have been arrested in connection with any of the fires.
