Samuel Luiz, 24, was assaulted while hanging out with friends in the city of La Coruna in the early hours of Saturday morning after an argument broke out outside a nightclub. He later died in hospital.
After his death sparked outrage across Spain, Catalan police were investigating yet another attack that may have been motivated by homophobia.
Mr. Luiz was killed after an argument with passers-by degenerated into a fatal assault.
When he made a video call outside the club, two passers-by accused him of attempting to film them and he was assaulted by one of them.
He ended up with a badly bruised face, but a few minutes later the assailant returned with 12 other people who beat the student nurse until she passed out. He died a few hours later.
The attack, which is the subject of a police investigation, has sparked outrage across Spain and led to demonstrations on Monday night in Madrid, Barcelona, Valencia, Salamanca, Bilbao and Zaragoza.
The demonstrators carried signs that read: “No more deaths for hatred, intolerance or discrimination. “
Diego Rubio, 21, who joined the protest in Madrid, carried a poster saying: “They stole our teenage years, now they are stealing our lives. “
The protest in Madrid erupted into clashes between riot police and protesters, prompting demands for an explanation from politicians in the capital.
Spanish Prime Minister Pedro Sánchez condemned the murder and offered his condolences to the friends and family of Mr. Luiz.
“It was a savage and ruthless act. We will not take a step back in terms of rights and freedoms and Spain will not tolerate this.
Max Luiz, the victim’s father, said: “They put out our only light. I just hope his death is not in vain.
Flowers and other tributes were laid at the location where Mr. Luiz was attacked in La Coruña.
A message read: “They will have to pay for this crime Samuel. “
José Miñones, the Spanish government representative in Galicia, said police were investigating whether the attack on Mr. Luiz was motivated by homophobia.
Spanish police announced on Tuesday that they had arrested three men for the murder. Between five and twelve men were believed to have participated in the fatal attack.
In another incident in Sant Cugat, a town north of Barcelona, a man was assaulted after refusing to hand over his phone and hand out cigarettes. He has been called derogatory names associated with homophobia on several occasions, police said.
He had a broken tooth, bruises on his arms, legs and head.
The Mossos d’Esquadra, the Catalan regional police force, said they were keeping an open mind about motivation, but said it could be a hate crime.
Mr Luiz’s murder came less than a week after the annual Spanish pride celebrations and days after Mr Sánchez’s left-wing government approved a bill to protect and strengthen people’s rights LGBTI +.
Data from the Spanish Interior Ministry revealed 278 hate crimes related to sexual orientation or gender identity in Spain in 2019, an 8.6% increase over the previous year.
The European Union’s Fundamental Rights Agency warns that only a fraction of hate crimes are reported to the police.
