Miami Beach: A locked safe has been found in the debris of a Miami Beach mansion once owned by Colombian drug lord Pablo Escobar.

Demolition began last week on the waterfront property now owned by Chicken Kitchen founder Christian de Berdouare.

Yesterday, excavators found the metal safe as they knocked down the last walls.

Excavator operator Miguel Mato tells El Nuevo Herald that the 2-foot-by-2-foot (0.61-meter) safe weighs up to 317.5 kilograms. Mato says he noticed it when the floor sank beneath some rubble.

De Berdouare and his wife say the safe will remain locked in a bank vault until they finish filming a documentary about Escobar's link to the property.

U.S. authorities seized the property in 1987. De Berdouare bought it from a private owner in 2014 for USD 9.65 million.
