Spanish police have found €25 million ($35 million) in Madrid that belongs to a drug gang based in Miami, according to the Associated Press.
It is the biggest seizure of cash ever during a police raid in Spain.
17 people were arrested in Spain, and four were arrested in the United States in a joint effort.
Police said that the gang sold cocaine from Colombia, and used the proceeds to buy and sell luxury cars.
The bust-up was helped by the fact that one of the gang leaders was caught at the Miami airport on the way to Madrid with €21 thousand in his briefcase, according to the New Miami Times.
