The Empire Boulevard Operation had continued to expand through 1979 and 1980 until the warehouse serving as its headquarters was raided by agents from the Newark branch of the FBI in the summer of 1980. The FBI had been surveilling the warehouse and some of the men unloading vehicles there and had shortly thereafter obtained a search warrant. Henry Borelli and Frederick DiNome were arrested in May 1981 for their roles in the operation, but there was not enough evidence to arrest any of the other active partners. DeMeo ordered Borelli and DiNome to plead guilty to the charges in hopes that it would stop any further investigations into his activities by the FBI or other law enforcement agencies.
