Cambridge police used pepper spray to disperse a mob of more than 1,000 people that turned violent Monday while waiting for an appearance by rapper Desiigner and Celtics rookie Jaylon Brown.
People started breaking glass and throwing bricks at officers at around 6 p.m. and officers responded with pepper spray. The crowd became aggressive when a number of people surged forward to try to gain access to the ticketed event with Brown and Desiigner, knocking over barriers and stomping over people waiting in line.
No police were injured. Some people were treated for exposure to pepper spray, police said.
"Attendees were treated after being exposed to OC spray, which was used by police to manage and disperse the crowd inside the mall after the crowds grew more aggressive," police said in a news release.
Mall officials were not immediately available for comment on Tuesday.
Police arrested six juveniles on charges of trespassing, disorderly conduct and disturbing the peace.
It took police about two hours to disperse crowds. State Police, MIT police, Harvard police and Somerville police also responded to clear the mob.
