A Guardia Civil macro-operation in Huelva province left up to 31 people detained.[1] A later account put the 31 detentions at 25 in Huelva, two in Seville, two in Algeciras, one in Granada and one in Malaga, for alleged drug-trafficking, criminal-organisation, weapons, money-laundering, smuggling, forgery, receiving and vehicle-theft offences.[2] The operation aimed to dismantle a major criminal organisation active in cocaine and hashish trafficking.[1]

About 300 Guardia Civil officers took part, alongside Colombian and Panamanian police officers through the GDIN intelligence-sharing project.[1] Officers carried out 18 searches for drugs and people connected with trafficking.[1] The searches covered Huelva city, Moguer, Trigueros, Gibraleon, Beas and San Juan del Puerto.[1] Officials later said the 18 searches spanned ten municipalities in four provinces, with cooperation from the US DEA, Colombia, Europol, France and Portugal, Guardia Civil units and Customs Surveillance.[1]

Across the investigation’s actions officers seized 278 kilograms of cocaine, 3,831 kilograms of hashish and 180 cannabis plants, plus more than 500,000 euros in cash and several weapons of war.[2] The first-day account reported 29 kilos of cocaine and hashish combined, plus properties, more than ten vehicles and firearms.[1] The proceedings were declared secret and are directed by Huelva’s Instruction Court No. 5 and the Huelva anti-drugs prosecutor.[1]
