The Wheeling Fire Department is investigating a fire that occurred on Wheeling Island early Wednesday evening.

Around 6:35 p.m., firefighters were called to 22 Zane Street after calls were made to the 911 center for reported heavy smoke in the area.

When firefighters arrived on scene, flames could be seen coming from the rear of the apparent vacant structure. Firefighters continued to suppress the fire mostly from the exterior throughout the evening because of the building being unstable and unsafe. Crews were able to get the fire mostly under control in about two hours.

No firefighters were injured. Fire investigators will work to determine a cause of the fire, which would take several days.
