Biggest Robbery Ever

Bristish police are looking for clues after one of the nation's biggest robberies ever, and they're offering a reward of 3.5 million dollars for information.

Thieves impersonated police officers and stole as much as 74 million dollars yesterday from a cash center near London.

They allegedly got the center's manager to help them, by threatning to hurt his family.

Police are studying security camera footage from the site.
