The Guardia Civil and National Police dismantled 497 criminal organisations in 2013 and detained 6,292 people for drug and human trafficking, said Security Secretary Francisco Martinez last Thursday talking to the media. Police operations to crackdown on organised crime in Spain had a 97 per cent success rate, he added. As much as 83 per cent of all groups dismantled had been operating for less than three years, while seven out of every 10 criminal organisations were made up of nationals from more than two different countries. Most criminal organisations were based in Barcelona and Madrid, followed by Cadiz, Malaga, Alicante, Valencia, Sevilla and Murcia. The large majority of them traffic in cocaine (31 per cent) and 21 per cent traffics in hashish, said Martinez. Following the nationwide operations launched last year to crackdown on organised crime, Spanish police seized almost 20 tons of cocaine, 146,708 kilograms of hashish, 103 kilograms of heroin, more than 10,000 ecstasy pills, 2,102 cars, 119 boats, six aircraft, 558 guns, 630 knives, 909 computers, 4,498 mobile phones and €30 million. Data show arrests for human trafficking also increased last year, with as many as 753 people detained or 33 per cent more than in 2012, said Martinez. A total of 1,180 victims - most of them Romanian, Chinese and Spanish nationals - were freed from the clutches of these criminal organisations, he added.
