The Times Herald of Port Huron reports that police received complaints of paintballs being fired inside and outside of vehicles in the city about 55 miles (90 kilometers) northeast of Detroit. Paintball guns and marijuana were found in two vehicles stopped by police. One man was charged and four others ticketed this week in Detroit after paintballs were fired at an unmarked police car. Detroit Chief James Craig referred Friday to the running battle as "Paint Up, Guns Down." He said organizers pitched it as an alternative to gun and other violence.
