Phoenix Police Chief Jeri Williams said a small group of individuals made "a choice of criminal conduct" by throwing rocks, bottles, and gas at police officers after President Donald Trump concluded his speech Tuesday night in Phoenix.
She said Phoenix officers responded with pepper balls and pepper spray to disperse the people and to protect themselves.
Phoenix police said after the speech people outside the convention center began to throw projectiles at officers.
Someone in the crowd dispersed tear gas in the area; the first gas dispersed was from someone in the crowd and not from officers, according to police.
Police say someone in the crowd began to topple pedestrian fencing that had been placed to block the roadway to create a safety zone surrounding the convention center.
Warnings were given by police to disperse as fights were occurring within the crowd.
Officers responded with additional tactics including tear gas and flash bangs which are used to create sound and light but not harmful effects.
Police say no rubber bullets were used by officers.
