City of Warren officials are aware of an intermittent odor in the area of Oak Street, Elm Street and Lexington Avenue.

The smell is intermittent which is proving an additional challenge in locating the source.

City Manager Nancy Freenock said that Department of Public Works crews have been trying to find the source for a couple months. She said crews searching on Tuesday didn’t smell anything in the area until a manhole cover was lifted.

A complete story will appear in Wednesday’s edition of the Times Observer.
