Contrary to its portrayal in some movies, Interpol has no police force that conducts investigations and makes arrests. Rather, it serves its 188 member countries by working as a clearinghouse for police departments in different nations to share law enforcement information — like files on wanted criminals and terrorists, stolen cars and passports, and notices that a law enforcement agency has issued an arrest warrant for a fugitive.
In the United States, a bureau at the Justice Department staffed by American officials transmits information between law enforcement agencies and Interpol. If a foreign country issues an arrest warrant for a person inside the United States, it is up to the United States government, based on its own laws, to decide whether to apprehend the suspect.
“We don’t send officers into the field to arrest people; we don’t have agents that go investigate crimes,” said Rachel Billington, an Interpol spokeswoman. “This is always done by the national police in the member country under their national laws.”
