A Canadian was one of three persons detained Monday on allegations that they were engaged in growing marijuana.
Agents of the Judicial Investigating Organization confiscated 322 marijuana plants that had been growing hydroponically under artificial light.
The law enforcement action was in San Gerardo de Rivas de Pérez Zeledón. Agents said they had been on the case since they received a tip about suspicious activity in December. They entered the property at 5:30 p.m. Monday and said they found the marijuana growing in a storage facility near the home.
A man and a woman, both Costa Ricans, were detained along with the 40-year-old Canadian, they said. The names have not been released officially.
