The supply of cocaine for weekend parties in the southern zone has been restricted.
The Policía de Control de Drogas said they detained seven men and three women to take down an elaborate network of drug sales throughout Osa, Palmar Norte, Palmar Sur, Ciudad Cortés, Corredores and Paso Canoas.
The cocaine sales were to repeat customers, the police agency said.
Police agents conducted nine raids to make the arrest. They also confiscated a firearm and quantities of cocaine and crack.
