Federal authorities seek an Ohio man believed responsible for starting an arson fire by throwing at least one fire-causing device through the windows of a city hall in north central Ohio.

Police Chief Phil Messer says something similar to Molotov cocktails started the small fire and set off sprinklers that caused water damage at Mansfield City Hall shortly before 1 a.m. Monday.

Special Agent Kim Riddell of the U.S. Bureau of Alcohol, Tobacco, Firearms & Explosives says authorities seek 40-year-old Kevin D. Dye on a warrant charging aggravated arson and manufacturing a dangerous ordnance.

Messer says four second-floor windows were broken at the Mansfield Municipal Court, including judges' administrative offices. There were no injuries.
