Police arrested a National Guard non-commissioned officer after a pistol and a hand grenade were discovered hidden in the ceiling of the showers at a barracks outside Nicosia.
A court in Larnaca remanded the master sergeant in custody for six days. He has denied any wrongdoing.
The case was reported to police by army authorities on August 1. During repair work to the ceiling in the showers, workers found, wrapped in waterproof material, a revolver, a hand grenade, explosives, a hood, and smoke grenades.
The items were collected by police and underwent forensic tests, including collection of DNA samples, which were later matched to the suspect.
Police told the court that the master sergeant moonlighted as a bouncer at an establishment in Limassol that authorities had had their eye on.
