Investigation Underway Into Cause of Gas Odor in Londonderry

An investigation is underway into what caused an odor of natural gas to spread throughout Londonderry.

The smell was reported in several areas Monday and as a precaution, gas service was shut off in multiple buildings.

The fire department says that while the odor was apparent, no gas leaks were uncovered.

Liberty Utilities also says there were no issues reported with its system and that crews will keep working to determine the source of the smell.
