TEMPE, AZ (3TV/CBS 5) -- Seven people were arrested Monday night after demonstrators clashed with police during a protest in Tempe.
The demonstration was organized by Tempe Against Police Violence, Black Lives Matter PHX Metro, Young Democratic Socialists of America and Direct Action Arizona.
The protest started peacefully at Tempe Beach Park around 5 p.m. But things became unsettled as the crowds moved off the sidewalks and into the streets.
The crowd moved onto the bridge over Tempe Town Lake, and officers ordered them back onto the sidewalks. Tempe police tweeted that protesters near Scottsdale Road and Playa Del Norte Drive had been warned by officers to disperse and exit the roadway. Police tweeted: "Participants will NOT be allowed to enter the roadway on Scottsdale Rd in either direction and MUST remain on the sidewalk."
But the crowd did not stay on the sidewalk and moved into the roadways. People in the crowd moved toward police on bicycles, yelling profanities and throwing things at officers.
During the melee, Tempe police say that one officer was injured when an unknown projectile thrown by protesters struck the officer in the face, causing a laceration requiring medical attention. Tempe Police Chief Moir tweeted that throwing objects at her officers is "unacceptable and not okay."
At one point, officers were seen tackling a protester who was wearing a football helmet and carrying a skateboard.
Police used oleoresin capsicum which is OC spray or better known as pepper spay, in an effort to push the crowd back.
Police made seven arrests for disorderly conduct, hindering and interfering with police, resisting arrest, and aggravated assault. According to police, once arrestes were made, protesters started to disperse from the roadway.
Police were also seen using pepper spray to try to disperse the crowd. Many protesters were carrying umbrellas, possibly to disguise their identities or to protect themselves from pepper spray.
Authorities have identified DPS trooper George Cervantes, a 15 year veteran, as the trooper involved in the shooting death of Dion Johnson, 28.
The event was held to demand justice for Dion Johnson and for Dalvin Hollins. A statement from organizers said that "This is not a family-friendly event and you must be 16 or older."
Dion Johnson was killed by a DPS trooper on in May. A statement from protest organizers said his birthday would have been tomorrow.
The man shot and killed during an officer-involved shooting in Tempe been identified as 19-year-old Dalvin Hollins. The incident began Wednesday morning.
Dalvin Hollins was killed on July 27, 2016 by Tempe Police Lt. Edward Ouimette. The case is in final stages in federal courts.
Organizers of Monday's protest are demanding that officers involved in those deaths by fired, the end of officer qualified immunity, the termination of all officers who are "accomplices to wrongful death or use of force violations," and that police officers should not be dispatched for mental health or substance abuse calls.
It is unacceptable to hurl projectiles at people- cops are people there to protect free expression and provide public safety. When you throw objects at them, that is NOT OK. https://t.co/cJ4c2kvOhh— Sylvia Moir (@ChiefMoir) July 28, 2020
