MERRILL (WAOW) -- Merrill firefighters and Wisconsin Public Service crews say they don't know what caused a possible gas leak Tuesday evening or where it started.
Merrill firefighter Rick Sparks told Newsline 9 the department received numerous reports of the smell of natural gas. The first reports came in after 6:00 p.m. Tuesday, Sparks said.
Sparks said firefighters closed a residential area while WPS crews investigated, but that area has reopened. That area extended from Highway 51 and Highway K to the north, to the south at Highway K and Duginski Road, to the west at Hillside Drive and Highway K, and to the east at Pope Road, Sparks said.
Crews say they searched for the cause for four hours Tuesday night. WPS then tested the area and reports say officials found very little odor gas in the hazard zone.
No one was evacuated from the area, Sparks said. Fire crews report leaving the scene around 10 p.m. Tuesday night.
Merrill fire officials tell Newsline 9 crews will be back on scene Wednesday to try and pinpoint the cause.
