Saturday, April 28, 2012 Arson investigators were working the scene of a suspicious house fire that injured a firefighter this morning near Jackman and West Alexis roads in West Toledo, authorities said.

The firefighter, whose name was not released, was taken to Mercy St. Vincent Medical Center with what appeared to be minor injuries, Toledo fire Lt. Tom Kuhman said. The victim had second-degree burns to the leg, according to initial reports from the scene.

No one was home when fire crews arrived about 8:19 a.m. and saw flames coming from the bedroom in the back of a single-story brick house at 5818 Livingston Dr. Firefighters attacked the blaze and mostly extinguished it by 8:24 a.m., about which time they rescued a "pit bull" puppy. The dog, which was brought out in a cage, was unhurt, Lieutenant Kuhman said.

As of 9:30 a.m. firefighters remained on the scene, making sure hot spots didn’t rekindle.

The cause of the fire was believed to be suspicious. Arson investigators were called to the scene, the fire lieutenant said.
