First responders from the Niles Fire Department and the gas company are looking for the cause of an odor that spread through part of the city early Wednesday.

People living around the area of Warren Avenue, just east of Waddell Park, reported smelling the odor at around 8 a.m.

Firefighters say they are inspecting a gas well in the area to try to determine if that is the source of the odor.

No homes have been evacuated during the investigation.
