(CNN) -- A replica of a World Cup trophy seized by Colombian authorities at the Bogota airport was made of cocaine, police said.

Gold paint in "bad condition" on the trophy's surface aroused the suspicion of investigators, who sent a sample of the trophy to a laboratory for forensic testing, the Colombian National Police said Saturday.

Results revealed that the replica was made of 24 pounds (11 kilograms) of cocaine, police said.

The 14-inch (36 centimeter) replica was packed along with several team jerseys in a shipment headed to Madrid, Spain.

The real trophy, designed by Italian artist Silvio Gazzaniga, is the same height, but is made of solid 18-carat gold and weighs 13.6 pounds (6,175 grams). It bears the engraved year and name of each World Cup winner since 1974, according to FIFA, the international football federation.
