Washington (CNN) -- Two current and two former TSA employees have been arrested in an alleged drug and bribery scheme by screeners who allowed large shipments of narcotics to pass through security at Los Angeles International Airport in exchange for cash, federal prosecutors said. Three other people, suspected drug couriers, are allegedly involved. One is in state custody. A second is expected to surrender on Thursday. Authorities are searching for a third. According to a 22-count grand jury indictment unsealed Wednesday, the Transportation Security Administration employees took payments of as much as $2,400 to allow suitcases filled with cocaine, methamphetamine and marijuana to pass through X-ray machines at LAX while TSA screeners looked the other way.
