Authorities suspect a natural gas leak caused an explosion at a commercial building on Detroit's east side Tuesday shortly before 9 a.m., injuring three people, WWJ reports.
The incident happened at the National Fleet Services, trucking-related company, at Grinnell and Grace avenues, off Gratiot Avenue just north of I-94.
“It appears to have been a natural gas leak, compressed natural gas,” said Second Deputy Fire Chief Craig Daughtrey, according to WWJ's Mike Campbell. “The contractor there does conversions, converts gasoline vehicles to natural gas vehicles, and one of their tanks exploded, it appears.”
Authorities said only three people were in the building.
