A detached garage with a vehicle inside was completely destroyed in a fire and two adjacent garages sustained minor damage in Winthrop Harbor Thursday evening, fire officials said.

The Winthrop Harbor Fire Department responded around 9 p.m. Thursday to the 800 block of Franklin Avenue in Winthrop Harbor for a garage fire.

Firefighters arrived and found a detached garage in the alley that was heavily involved in flames, Winthrop Harbor Deputy Fire Chief John Lewis said.

The flames were blowing across the alley.

Additional fire departments in the area responded to assist.

Crews deployed hose lines and extinguished the fire in 30 to 45 minutes, Lewis said.

Two adjacent garages sustained damage to their siding due to excessive heat.

Embers also landed on the roof of a nearby home, Lewis said.

The garage that caught on fire, which housed a vehicle, was completely destroyed.

No one was injured, Lewis said.

Initial reports indicated a resident may have been trapped inside the garage, but it was later determined they were in an adjacent home not threatened by the fire.

A damage estimate or cause of fire was not immediately available and the incident remains under investigation by the Winthrop Harbor Fire Department.

The Winthrop Harbor Fire Department was assisted at the scene by the Beach Park, Gurnee, Newport Township, Pleasant Prairie and Zion fire departments.

The Libertyville and North Chicago fire departments provided coverage to Winthrop Harbor during the incident.
