Twenty-five-year-old Nelson Delgado is alleged to have pulled a knife on a group of Brits he believed were responsible for glassing his brother earlier on that night.
The stabbings are said to have taken place outside a pub in Magaluf at 4am Friday morning, the UK’s Mail Online reported.
Twenty Brits were involved in a brawl which ended up with five of them in hospital, two of whom are critical with stab wounds to their back and abdomen.
Delgado, who is thought to have grown up in Britain, has been remanded in custody but has not yet been charged with any crime.
Magaluf is one of Spain’ most popular holiday destinations for young Britons looking for sun, sea and sex.
The alcohol-fuelled nature of their trips is the main reason behind a recent spate of tragic falls from hotel balconies.
Nine people have died in Majorca this summer in what the Spanish press is referring to as a growing trend in “balconing”.
Balconing usually involves either jumping from one balcony to another or leaping from a balcony into a hotel swimming pool.
Drug trafficking and sexual assaults are also on the up in Majorca’s ‘low-cost’ holiday resorts.
Local Majorca Police and Spanish Civil Guard officers have had to increase their night patrols this summer to try and restore order in an increasingly wild Magaluf.
