Twelve people were arrested during the holiday weekend on suspicion of setting off fireworks and other charges that stemmed from firework violations.
A Columbia city ordinance bans fireworks from being set off in the city.
The suspects ranged in age from 14 to 26 and were arrested between 7 p.m. Monday and 2:30 a.m. Tuesday.
Nine of the suspects arrested were juveniles. A 16-year-old was charged with possession of cocaine and marijuana after being arrested for a firework violation.
The number of incidents was significantly lower than past years, said Capt. Brad Nelson of the Columbia Police Department. He estimated that they arrested two to three times more individuals last year for fireworks or other offenses.
He said he believes the lack of major disturbances, such as serious firework-related assaults or vandalism, was because the holiday was on a Monday. He also attributed the drop in firework incidents to the enforcement of firework violations starting on July 1 and the possibility of rain Monday.
