Bathers on Las Américas beach Playa de Troya were surprised and concerned by the discovery around 6pm yesterday of a grenade on the beach. A member of the public came across it and alerted the authorities … who arrived with great speed. The Guardia Civil’s Submarine Special Activities Group removed it and it is now being analysed by specialists to try to determine its origin and nature. The beach was cordoned off while this was taking place. Thankfully the only thing that was blown up was excitement and some fear!
