An undercover police officer dressed as the Grinch makes a drug bust, seen arresting members of an alleged drug-trafficking gang.

The Dr. Suess character was seen breaking through a door with a sledgehammer in Lima, Peru before making arrests.

The Grinch then located the drugs before posing with the alleged criminals.

"Three drug dealers that are now in custody... [The officer] managed to go unnoticed disguised as the Grinch," they announced.

The drug bust is reportedly an ongoing tradition where agents dress in costumes to make arrests on Halloween and Christmas.
