Officers stationed at an Anaheim park to monitor a planned Ku Klux Klan rally called for backup as when the event turned violent. Additional units arrived at the scene 1 minute and 36 seconds after the first report of violence was received, police said.

Three counter-protesters were stabbed while clashing with KKK members, one of whom was hospitalized after being stomped when the rally turned into a melee at about 12:10 p.m. Saturday at Pearson Park, 400 N. Harbor Blvd., according to Anaheim police Sgt. Daron Wyatt.

A dozen people were arrested, but five, including a male juvenile were ultimately released after investigators poured over evidence, including video provided to police at the scene or posted on websites. The child was arrested again this afternoon and booked at juvenile hall on suspicion of assault with a deadly weapon, Wyatt said.

“This arrest stems from additional video evidence of the juvenile’s actions and his involvement in the violence,” Wyatt said.

Of the rest, who were booked on suspicion of assault or elder abuse because a stomped KKK member was over 65 years old, only one was from Anaheim, Wyatt said.

One of the injured counter-protesters was rushed to a hospital in critical condition after being stabbed with an eagle ornament at the end of a pole holding a Confederate flag, but his condition was later upgraded to stable. The other two were in stable condition when taken to a hospital, Wyatt said.

Although only counter-protesters were stabbed, Wyatt said the group, which numbered 10-20 compared to less than 10 KKK members, was believed to have initiated the violence.

Wyatt said six marked Anaheim police units were at the scene within two minutes after the trouble started.

“Additional units continued arriving over the next few minutes,” Wyatt said. “Officers rendered medical aid to those who were injured and arrested all but one of the suspects who were engaged in the majority of the violence.”
