Police in Spain have broken up a gang that was allegedly building semi-submersible drones, each capable of ferrying up to 200kg of drugs across the strait of Gibraltar. The Policía Nacional, which arrested eight people in Cádiz, Málaga and Barcelona, said it was the first time it had come across underwater drones being used to smuggle drugs. Officers also seized 145kg of hashish, 8kg of marijuana, €157,370 in cash, and six large aerial drones that could cover a distance of 30km
