Maine authorities say a Waldoboro man has been arrested a second time in a little over a month on charges of selling the drug bath salts. The Maine Drug Enforcement Agency says Bradford Davis, 37, was arrested Wednesday at his home. He’s charged with trafficking bath salts and violating his prior bail conditions. Drug Enforcement officials say police seized 20 grams of bath salts. Davis had been free on bail after his Jan. 17 arrest when drug agents said they seized 44 grams of the drug from him. He was being held without bail after his most recent arrest.
