A stark warning has been issued to students against getting involved in the drugs trade, after a suspected Ibiza drugs ring was smashed and 25 people - including two from Ireland - arrested.
During a major operation on the Balearic party island, 38,000 ecstasy tablets were seized - along with 8.8lb (4kg) of cocaine, 8.8oz (250g) of ketamine, 7 pints (4l) of GHB, and 1.8oz (50g) of crystal MDMA.
About €56,000 (£45,840) was also recovered as part of Operation Arrow - a joint venture by the UK's Serious Organised Crime Agency (Soca) and the Spanish National Guard.
A dozen properties were searched in San Antonio de Portmany, Santa Eulalia and San Jose de Sa Talaia during the weekend operation, in which 20 Britons, a Spaniard, a Slovak and a Czech national were also detained.
Police believe they have rounded up the most active gang on the party island.
Ken Gallagher, head of European operations for Soca, said: "This joint operation has taken out every level of a gang that was responsible for supplying and distributing a vast quantity of drugs to Ibiza.
"It represents an excellent result for our co-operation with the Spanish, and serves as a stark warning to students and others who might think they can make some easy money through the drugs trade.
"These arrests could have significant impact on their future, on their ability to finish their degrees and on their prospects for employment."
He added: "It also clearly demonstrates that career criminals who seek to avoid the attention of UK law enforcement by basing themselves overseas are well within our reach."
The drugs ring is understood to have been led from the UK with two branches in Ibiza - one in charge of establishing contacts and another responsible for distributing the drugs.
These were smuggled on to the island in cars coming from the UK or in the luggage of British tourists flying to Ibiza. One young British woman is alleged to have carried 6.6lb (3kg) of cocaine through the airport before she was halted on August 8.
Alleged gang members living overseas are believed to have visited the island to supervise the operation and collect its proceeds.
While those at the top enjoyed luxurious accommodation, dealers were housed in flats and apartments in popular holiday spots.
They are believed to have kept some substances for daily distribution but most were placed in secure houses.
The police raids came after a surveillance investigation was launched in September, when the Civil Guard dismantled a British organisation involved in drug trafficking in Ibiza.
Authorities believe their suspects were trying to build the necessary infrastructure for drug distribution during the summer months.
A Spanish police statement said: "The ring used young 'public relations' people in nightclubs to distribute drugs and ensured similar prices were charged at each point of sale, depending on the time and place."
A spokeswoman for the Foreign and Commonwealth Office said the department was aware of the arrests and was offering consular assistance.
