The Moline Fire Department is investigating the cause of an attic fire Friday morning.

Firefighters responded to 5403 3rd Ave. at 9:37 a.m. where a fire broke out in the attic, Capt. Mick Dochterman said.

The two-story, wood-frame home is divided into three apartments, and five residents escaped unharmed, Dochterman said.

The fire was contained to the attic, Dochterman said.
