The Tucson Police Department is investigating several arsons, including one fire in February that caused more than $1 million in damage to a warehouse building in the Lost Barrio district, authorities said.

Arson investigators are asking for assistance in locating suspects who might be connected to at least four arson fires dating back to November, said Officer Chuck Rydzak, a Tucson Police Department press release.

The Feb. 24 fire in the historic Lost Barrio district heavily damaged at least three businesses in the warehouse, which is known for its unique shops and high-end imports.

Tucson police also are investigating these fires:

• On Nov. 11, a fire burned a tattoo shop in the 6100 block of East 22nd Street. Investigators found three gas containers that had been thrown through a window to ignite the fire.

Two men were seen leaving the property, possibly in a white Chrysler LeBaron sedan.

• On Jan. 15, police responded to an arson at an unoccupied house in the 1600 block of North Andros Place.

• About two weeks later, a trailer home in the 500 block of East Mojave was burned after the homeowner left for work. Neighbors reported hearing popping sounds, and seeing two men jumping a fence and fleeing in a dark sport utility vehicle.

Detectives also believed the home was burglarized.

Anyone with information is asked to call 911 or 88-CRIME.
