OAKDALE, Minn. — A couple dozen unruly juveniles raised havoc at this east St. Paul suburb’s annual summer fireworks. Authorities regain control only after Police Chief Nick Newton called in sheriff’s deputies from two neighboring counties and police from nearby Woodbury and Maplewood. Newton acknowledged that festival-goers, mostly families with children, were in fear and panic. This was after sunset at Walton Park. No injuries were reported. Newton said his 31-officer department would be investigating how things got so out of hand. He said he had pre-assigned “a full contingent” of officers at the park. During the melee there was a report of people with guns, but Newton said he had.no confirmation of the reports.
