Interpol says it will help Olympic organisers with security and in cracking down on doping and match-fixing.
The international police agency says in a statement on Thursday that it signed a deal with the International Olympic Committee to cooperate on security.
The deal does not specifically target the Winter Games in Sochi, Russia, which start next week.
Interpol, based in Lyon, France, acts like a clearinghouse for information from national police forces around the world.
The deal with the IOC says it will focus on identifying potential doping and match-fixing and attempted corruption of officials and players.
The IOC is putting up $20m to fight doping and match-fixing - considered the two biggest threats to the credibility of the Olympics.
