INTERPOL is the international police organization whose duties include assisting with the prevention of international crime as well as assisting member states with identifying and approaching fugitives in other states. Normally fugitives are identified at airports or other transit areas.

An Interpol notice can hinder a person's facility to travel and may subject them to arrest. Interpol notices maybe issued following a conviction or warrant.

Types of INTERPOL notice:

Red notice

Issued to request the arrest of internationally wanted persons.
Blue notice

Issued to request further information regarding an individual involved in a crime
Green notice

Issued to dispense warnings and to offer intelligence about individuals who have been involved in a crime and are likely to repeat the offense(s) in another country.
Yellow notice

Issued to enlist assistance in finding missing persons, or identifying people who are not currently able to identify themselves.
Black notice

Issued to request information about unidentified bodies
Orange notice

Issued to warn international police organizations about potential threats, including dangerous materials, bombs and disguised weapons.

Interpol-United Nations Security Council Special Notice

Issued for individuals or groups of people who have become targets of UN sanctions against Al Qaeda and the Taliban.

One of the problems that a criminal arrest, accusation or individual abroad may create is the inability to travel internationally. Persons involved in a criminal case in a foreign country may find themselves subject to not only the laws of the state where they are being accused, but are also subject to detention in the airports of other countries. This situation results from the application of Interpol regulations.
