Spanish authorities announced today, Wednesday, the arrest of Óscar Sánchez Gil, head of the fraud and anti-money laundering division of the National Police, after €20 million was found hidden in the walls of his home.

This comes as part of an investigation linked to Spain’s largest-ever cocaine bust, where authorities seized 13 tons of cocaine hidden in shipments of bananas from Ecuador.

Sánchez Gil and his wife, who also works as a police officer, have been charged with drug trafficking, money laundering, and membership in a criminal organization.
