Two cars and an SUV burned in an early morning fire in the 900 block of Church Street in Ann Arbor, the Ann Arbor Fire Department reported.

Firefighters responded to a call shortly before 2 a.m about a car on fire that was parked in a parking area beneath an apartment building. While en route to the fire, another call came in saying the building was on fire.

When crews arrived, the parking lot area was engulfed in flames and the fire was starting to spread up an exterior wall of the building, according to a press release from the fire department. Two cars and an SUV were found to be on fire.

Ann Arbor Assistant Fire Chief Greg Hollingsworth said the car fire was suspicious because the vehicle that first caught fire had not been driven for a couple days, meaning it likely wasn't a mechanical or overheating issue that caused ignition.

Hollingsworth said investigators are looking into any possible connections between car fire and another house fire that happened a few hours later on South State Street.

The fire remains under investigation and damage estimates were not immediately available.
