BOGOTA, Colombia - Colombian police Tuesday found about $19 million belonging to a drug trafficking group buried under a house in the southwestern city of Cali, the second such discovery in less than a week.

Police said they arrested nine people who were in the house.

On Friday, police found $16 million hidden in a modest house in Cali, the country's third-largest city about 185 miles southwest of Bogota.

Cali has been a center of Colombia's illegal narcotics industry since the days of the Cali cartel, dismantled in the 1990s.

Colombia is the world's largest producer of cocaine.
