For the second time in two months, fire crews are downtown in Cleveland because there's a strong smell of gas in the air.
St. Clair is reportedly shut down near W. 9th as the investigation into the mysterious odor continues.
The Cleveland Fire Department has received numerous calls Friday morning about a strange gas odor downtown, and crews have investigated several downtown buildings, but have not determined a cause of the odor.
No buildings have been evacuated, according to the Cleveland Fire Department.
Fire trucks blocked off streets in the Warehouse District around 11:30 a.m., but did not discover a gas leak or a fire.
