It came as a shock to the Colombian police when a grand piano, that was shipped as a part of household items, was found to have cocaine stocked up in its keys.

Colombian custom officers discovered 560 pounds of cocaine after the piano played an off note when the keys got accidentally pressed. The Miami Herald reported Tuesday that the cocaine, which is worth $5 million, was part of a shipment of household items originating in the capital of Bogota and destined for Panama.

No arrests have been made so far. The matter came into light when officials noted the piano to be suspiciously heavy and discovered the drugs packed into various recesses of the instrument.
