The Costa Rican government said it has seized a jet carrying more than a ton of cocaine and it detained the two pilots from Guatemala, according to the Associated Press.

The country's public safety ministry said the small plane was flying from Cali, Colombia, before it made an emergency landing Monday, Dec 16, at a private airstrip on the Caribbean coast.

The ministry said police detained a Guatemalan man and his adult son with 51 packages holding 44 pounds of cocaine each. The suspects are in the custody of prosecutors in the province of Limon.

Authorities say police determined that the jet belongs to the owner of a chain of retail stores in Guatemala and are trying to locate him.

Officers also suspect a criminal gang in the area helped the jet carry out the emergency landing.
