This is the best summary I could come up with:

Leftwing parties in Spain are demanding explanations after a video appeared to show a pair of police officers using violent force on two unarmed black men in a central Madrid neighbourhood.

The video, shot on Friday in Lavapiés, appears to show one of the men on the ground and immobilised by a police officer who seemingly has him in a chokehold.

As video of the encounter swiftly spread across social media, a police source told the Europa Press news agency that the two men had been arrested for undermining authority.

In questions submitted to parliament, Errejón noted that the video appeared to show “an aggression” by two police officers, carried out on one man he described as immobilised and another who was not resisting.

Errejón called on the interior ministry to clarify whether an investigation had been opened into the officers’ behaviour, asking: “What measures will be taken in response to citizen complaints regarding the existence of police violence against migrants in the Lavapiés neighbourhood?”

“This is a situation that we live daily,” said Serigne Mbayé, a former regional politician and now the antiracism secretary for Podemos, in a video posted online from the protest.
