Sounds like some unfortunate gang-related fights forced officials to close Havre de Grace’s carnival Sunday night in Tydings Park about an hour early, according to an account in the Baltimore Sun. It appears that not only did at least two fights break out – one by the bumper cars and another at the end of the race track — but that the fighting youths turned on police, throwing dirt and rocks at officers who came to break up the fights. The story said that one man actually attacked a police dog. About a dozen people were arrested, some of them wearing gang colors, and charged with disorderly conduct, The Sun reported. The melees occurred after the city’s fireworks display ended, and drew more than 60 officers from nearby departments to help clear the festival. The Sun story said Harford County Sheriff’s Office officials are suggesting carnival organizers set up entry points and conduct searches at next year’s festival. Although, I don’t imagine searches will stop teens from slugging each other or throwing rocks at police. Here’s to hoping that fireworks will be the only thing erupting at Bel Air’s Fourth of July celebration today.
