MADISON -- Madison police said a person of interest was arrested Tuesday night, June 30 in connection with an arson attack on the City County Building.
Police said Marquon Clark, 26, was arrested on a probation hold after a traffic stop near Verona Road.
While officers were trying to stop Clark's car, police said the driver of a pickup truck -- which was following behind Clark's car -- intentionally swerved at a marked Madison police squad car. The officer had to take evasive measures.
The truck's driver, identified by police as Conner Fleck, 25, of Pardeeville, was arrested for second-degree recklessly endangering safety.
The Bureau of Alcohol, Tobacco, Firearms and Explosives offered a $5,000 reward following the fire-bombing June 24.
