A Westerly man has apologized for hosting a party where some middle school students drank alcohol. Brian Holdredge, 41, was charged Friday with procuring alcohol for minors and violating the town’s social host ordinance. He was issued summonses to appear in District Court and Municipal Court. Westerly police said Holdredge held a birthday party for his daughter Jan. 31. About 30 young people attended, many of them 12 and 13 years old. Police said at least two children drank alcohol. Holdredge, a youth football coach and volunteer firefighter, told police he left some alcohol out after pouring himself a drink and later realized that some young people were drinking.
