Soccer Star Sergio Contreras Arrested In Drug Raid, 'Ton of Hashish'

Ex-soccer star Sergio Contreras -- aka Koke -- was arrested in Spain on Tuesday as part of a massive drug raid ... and cops say they recovered a TON of hashish.

Literally, a metric TON.

36-year-old Contreras is pretty famous in Europe -- he made a fortune playing for big teams like the Ligue 1 club Olympique de Marseille and the famous Greek team Aris Thessaloniki.

But, ever since his pro career ended in 2016, cops say he's been RUNNING a major drug ring out of Southern Spain.

On Tuesday, cops launched a multi-city raid ... nabbing 20 and seizing nearly $800,000 in hash, which is made from the resin of the cannabis plant.

Cops also recovered a stash of guns -- including pistols and rifles.

A source told the Associated Free Press that Contreras is the "head of the organization."

Contreras was taken into custody and is currently being held in Malaga, an upscale beach community.
