One police officer injured and five arrested in the most tense day in 17 days of camping in Sol

An injured police officer and at least five people arrested is the balance of the most tense day in 17 days of camping in Puerta del Sol, after several radical groups tried to break up the protest over the housing crisis.

The problems began when, at the end of the parade for the National Holiday, a group of people with Spanish flags, some of them unconstitutional, went to Puerta del Sol and surrounded those camped for two weeks shouting "Ceuta is not for sale" and "Face to the sun."

According to one of the campers, there have been "aggressions and provocations", which has required the action of the National Police, which has proceeded to arrest some people.

After the two hours of confrontation of chants, the National Police has dispersed the protesters, who have not stopped shouting at the campers, as well as the press: "Fucking shitty press, fuck you, manipulators, sons of bitches," they told the cameramen.

Among other slogans, they have chanted: "Dead red, fertilizer for my garden" or "Red that I see, red that I kick."

Tensions have continued in the afternoon, with both sides facing each other in the streets surrounding the square, to the point that the organizers of the camp have asked for help through social networks due to fear of being attacked.

As confirmed by Metro security sources, all access to this service and the Cercanías service located in Puerta del Sol have been closed for a time at the request of the Police, but early in the evening they have already reopened.

One of the greatest moments of tension occurred shortly before six in the afternoon on El Carmen Street where, after several races and throwing bottles, the Police arrested a young woman.

After 7:30 p.m. the situation became more complicated and the National Police troops deployed in the area were reinforced, advancing their positions so that people who wanted to access Sol could turn back towards the Plaza de Callao.

Although the security forces have controlled the episode, the hostile atmosphere and the chants have continued in the distance, while the riot police moved away the two groups, who continued chanting slogans such as "Madrid will be the tomb of fascism", on one side, or "dead red, fertilizer for my garden", on the other.

Throughout the afternoon, groups of protesters with Spanish flags, some of them unconstitutional, have approached Puerta del Sol, where a camp has been held since September 26 to denounce the housing situation in Spain.

From Alcalá or Espoz y Mina streets, the closest to this morning's parade, to Arenal or Preciados, the protesters have surrounded the square, unable to access it due to the strong police presence.

According to sources from the Mediation Commission for the protest in Sol, the protesters have rebuked the campers, who have formed a security cordon around the entire perimeter of the stores to protect them.
