That brought the total of suspects in a drug distribution ring to 15 because two already are in prison.
Anti-drug agents said they confiscated 4,525 doses of crack cocaine and marijuana. Also confiscated were a shotgun and two handguns. They also found more than 7 million colons, more than $14,000, and a luxury automobile.
Agents with help from other agencies raided and searched 14 locations. The Policía Control de Drogas said that the raids were in the El Roble and Barranca sections of Puntarenas Centro.
The investigation began in October with a confidential telephone call, said the Ministerio de Gobernación, Policía y Seguridad Pública. The action Tuesday was triggered by the arrest of a man and his female companion May 28. They were described as distributors of drugs.
Agents said that the network was headed by three brothers with the last names of Zapata Mora. The 17-year-old girl is a companion of one of the brothers and is, herself, a distributor, the agency said.
Many of those detained Tuesday have had prior contact with police, and two of the brothers have served jail terms, agents said.
Five judicial agents suffered injuries after the arrests when their pickup overturned on the Caldera-San José highway.
