HAMTRAMCK, Mich. (WWJ) – A Hamtramck firefighter was injured overnight as crews battled flames at two burning homes.

The fires broke out overnight at neighboring houses on Lumpkin, near I-75 and Holbrook. Fire officials say the first fire broke out in a vacant house, then spread to the other house — a multi-family unit.

The injured firefighter suffered smoke inhalation and was treated at the hospital and released. However, he won’t be returning to work right away.

No one else was injured. The cause of the fire is under investigation.
