Suspicious/Violent Persons

Suspicious/Violent Persons Emergency Information

Suspicious persons can be total strangers whose behavior and actions create a sense of fear, threat, or suspicion that they are about to or have committed a criminal act.  A suspicious person can also be an acquaintance, a friend, co-worker, student or anyone who is acting unusual, violent, or may appear to be emotionally distraught.  In any case, persons acting in a suspicious and potentially violent or criminal manner should be reported to UD Police immediately.

Suspicious behavior can occur anywhere on campus at any time.  Some of the behaviors to look for are:

  • Making verbal or non-verbal threats.
  • Suspected of having a weapon.
  • Fascination with weapons or violence.
  • Acting disoriented or confused.
  • Dressed unusually for weather conditions.  (Example: Heavy coat or clothing that could easily conceal weapons during warm weather.)
  • Carrying or in possession of unusual bags, packages or objects that might conceal a weapon or explosive device.
  • Appears to be casing an area for the purpose of committing a theft offense or other crime.
  • Extremely impaired from apparent use of drugs or alcohol.
  • Abrupt change in a person's demeanor or behavior.
  • Creating an intimidating, hostile, or offensive environment.
  • Accessing restricted areas or attempting to gain entry into a secured building, vehicle, or area.
