Five firetrucks lined Main Street on Monday as the Concord Fire Department investigated a potential gas leak downtown around 3 p.m., though no public threat was detected.
An alarm, which is supposed to sense and report dangerous levels of gas, alerted the department to the potential leak in the building that houses the Bangor Savings Bank near Eagle Square.
Captain Jonathan Sinclair said firefighters who’d entered the building didn’t find any evidence of a leak.
“No odors right now and no readings, so it could be that the gas detector that is tied to the fire alarm is bad,” Sinclair said around 3:30 p.m.
They were further investigating the possibility of carbon monoxide, which is odorless.
The same address, 82 N. Main St., had a gas leak in the street roughly a month ago, Sinclair said.
