URGENT N.J. OFFICE OF COUNTER-TERRORISM ADVISORY Re: POSSIBLE IMPERSONATION OF UPS PERSONNEL SEEKING ACCESS TO BUILDINGS The New Jersey Office of Counter-Terrorism has received a report of an attempt by an unknown individual to enter a government facility by falsely posing as an employee of the United Parcel Service. Based on this incident, security personnel should exercise heightened vigilance when screening all delivery personnel at the entrances to all buildings and when accepting deliveries. Such measures should include careful inspection of credentials and identification of all delivery personnel to ensure that they are who they purport to be.
