Spanish police said they broke up a network that financed the Serbian criminal outfit known as the Zemun clan with the profits from marijuana plantations on Gran Canaria island.

Police arrested 25 people and seized about 700 pot plants in greenhouses and open-air plots.

The investigation leading to the take-down of the criminal group was launched after the arrest last February of Luka Bojovic, mastermind of the 2003 assassination of Serbia's then-prime minister, Zoran Djindjic.

Bojovic also arranged the subsequent killings of the assassin, Valadimir Milisavljevic, and two other hitmen, in a bid to prevent authorities from tracing the crime back to him.

Seventeen of the arrests were made in Las Palmas, in the Canary Islands, eight in the cities of Benidorm and Villajoyosa, in southeastern Spain, according to police, who said that officers carried out 33 raids in which they seized 840,000 euros (about $1.1 million) in cash, 65 grams of cocaine, luxury watches and jewelry in two bank safe deposit boxes.

The investigators located three pot plantations, the largest of them having almost 500 plants in a multi-story house located in Las Palmas. EFE
