Judicial agents said that two men took a firearm and packages containing an unknown substance from a vehicle that had been impounded.
The robbery took place at the installations of the Ministerio de Obras Pública y Transportes in Zapote in eastern San José. The Judicial Investigating Organization said that two armed men held up a guard at the impound lot and then broke a window in the vehicle to obtain the 9-mm. pistol and the packages.
The car was the same one that had been stolen from a man April 25. He was attacked and suffered blows to the head. He is the owner of the firearm.
Later the vehicle turned up along the Caldera highway, and police took it into custody.
