A Sharon, Massachusetts, man pleaded guilty today to willfully retaining national defense information. Ahmedelhadi Yassin Serageldin, 66, an Egyptian-born nationalized U.S. citizen, admitted to removing classified national defense information from his workplace at a defense contractor without authorization and keeping it unsecured within his home. Serageldin was originally indicted and arrested in November 2018 on one count of misleading conduct with intent to hinder, delay, or prevent communications to a law enforcement officer relating to the commission or possible commission of a federal offense.
