Concord fire

Concord firefighters battle a blaze overnight Tuesday on Merrimack Street.

A former Concord firefighter alleges he was sexually harassed for years by coworkers and superiors and subjected to remarks on his perceived sexual orientation, according to a lawsuit filed against the city.

Christopher Golomb filed complaints at both the local and state level about being the subject of “gay” jokes “despite the fact that Mr. Golomb is not gay,” according to the filing.
