Fuerza Pública officers detained eight men after U.S. tourists were robbed at gunpoint on Playa Potrero, said the security ministry.
The eight were captured at the La Huacas crossing and appeared to be on their way to Tamarindo. The tourists lost personal effects and cameras, said the ministry.
The men were traveling in two vehicles. Officers said they confiscated a .38-caliber pistol and a radio scanner that contained the police frequencies.
Officers said they believed that the men would be suspects in a string of robberies of tourists in the area.
