Luiz was spending an evening with his friends in the town of A Coruña on the night between Friday and Saturday. He left the bar to make a video call on Saturday morning.
Two passers-by accused Luiz of filming them, and while Luiz explained that he was talking to a friend in a video call, another passer-by attacked him.

The protesters held signs that read, among other things, “Your homophobia is killing us”.
In Madrid, riot police attacked protesters with bombs, prompting the administration to launch an investigation into its activities.
