More than two dozen people were arrested in a prescription drug sweep that included a raid on a Boeing helicopter plant outside Philadelphia, an official with knowledge of the operation told The Associated Press on Thursday.
The official spoke on condition of anonymity because an announcement had not been made. Federal prosecutors scheduled a news conference for the afternoon with the Drug Enforcement Administration and the FBI.
The arrests happened Thursday morning at Boeing's plant in Ridley Park, just south of Philadelphia, which has about 5,400 employees. Workers there build aircraft including the H-47 Chinook helicopter and the V-22 Osprey. The plant, part of Boeing's Defense, Space and Security unit, is also the headquarters for its Rotorcraft division.
An official with Boeing's Military Aircraft division at the Ridley Park plant declined to comment on the raid. A message left for a spokesman for Boeing Defense, Space and Security was not immediately returned.
