Simian swat squads: India hires monkeys to guard Games venues

Official: Langurs are 'very effective way' to protect sites from other simians

“Security officials at the Commonwealth Games aren't monkeying around anymore, deploying langurs at several venues in New Delhi to keep smaller simians from causing any trouble.

Because they are large and fierce, langurs are often used in India to keep other monkeys in check in public places.”
