Authorities arrested three men in a buy-bust operation in Barangay Bantug Norte, Cabanatuan City.
The suspects, 18, 21, and 29 years old, had been under police surveillance.
An undercover officer posed as a buyer and successfully purchased dried marijuana at one of the suspects' homes using marked money.
This led to an immediate raid and their arrest.
Police confiscated over five kilograms of marijuana, valued at more than P600,000.
The suspects remain in custody and face drug-related charges.
They have yet to issue a statement.
