Two men from the Republic and nine British nationals are also being questioned over alleged drugs trafficking offences after the Guardia Civil operation on the Balearic island.
Thousands of pink 'rock star' tablets, similar to those believed to have caused the death of a young British girl and poisoning eight other individuals in Ibiza this July, were seized.
Cocaine, hashish and steroids were also uncovered when eight properties were raided in Sant Josep de sa Talaia and San Antonio de Portmany.
Precision scales, mobile phones and €69,000 have also been removed by police.
The detainees are alleged to be members of one of the most active gangs on the island - one which operates as the main supplier of cocaine and other designer drugs on the club circuit.
Enquiries were carried out on the basis of intelligence obtained by the Guardia Civil after other gangs involved in drugs trafficking on the island were dismantled.
The majority of these gangs were British and took advantage of the influx of young people during the summer.
It was revealed that the gang, which police say is now dismantled, only travelled to Ibiza in summer to meet the large demand for drugs on the island during this period.
According to the Guardia Civil, when some of the drugs were running short, other gangs based in the UK would send new batches via different methods.
Officers say this can be seen by the seizure of a package containing a kilogram of crystal MDMA on 22 July at Ibiza airport - it was seized from an individual who had travelled from the UK and allegedly aimed to supply the drugs to the individuals now detained.
