On Wednesday night, twenty-two police officers were injured and their vehicles were damaged after an illegal street party in Brixton, South London, descended into violence and chaos.

According to people who were at the event, the party started peacefully with a barbecue and music. After complaints from other residents, police officers encouraged the crowd to leave and they tried to break up the party. The majority of people left when the music was turned off; however, police officers said that they were confronted by a hostile crowd, and things got out of hand.

Four people have been arrested for assault and public order offences, and they remain in police custody. Two police officers and two other people required hospital treatment.

Difficult words: descend (to move or come down, to change suddenly), assault (a physical attack), public order (when there is not a lot of crime and violence among people).
