UPDATE 11:15 P.M.: As of about 11 p.m. on Tuesday, Shelton firefighters are searching for a gas leak in the Shelton Avalon apartment complex in downtown Shelton.
There is no active fire in the large residential complex on Canal Street. There had been a grease fire in one apartment earlier at Avalon, perhaps just before the reported gas leak, but that fire is not a factor at this time.
Emergency crews have been on scene since slightly before 10 p.m. Personnel from the local natural gas company, Eversource (previously Yankee Gas), also are there looking for the suspected leak.
The Avalon complex has 250 rental units inside one large sprawling structure.
