Fuerza Pública officers and the agency’s dog unit are continuing the search for drugs or guns in a section of Paso Canoas.
Police detained five men in the area Sunday night and confiscated six firearms, including an Uzi submachine gun as well as ammunition.
Police responded to calls from the area that two suspicious cars containing armed men wearing masks were circulating there.
The first detainees were a Costa Rican man and a Colombian man who carried a total of three firearms, including a 12-gauge shotgun.
Later they stopped a car in the same area and detained two more Costa Ricans and a man who probably is from Panamá, they said. Police on a later patrol found weapons near the site of the arrests. One of them was the Uzi.
Police are searching the area because they said they do not know why the men were there or what they were doing. They are seeking more weapons and perhaps drugs. The location in on the border with Panamá.
