The March 14 beating in Palmdale was captured on video and posted on YouTube, but has since been removed from the site. The seven boys, ages 13 to 16, were arrested Wednesday for investigation of assault and committing a hate crime, Lt. Don Ford said.
The attack happened near Cactus Middle School, but Ford didn't know if any of the teens involved were students there.
The video shows as many as 10 boys surrounding the victim and challenging him to a fight. The suspects then began hitting the teen while others watched.
During the beating, the teens made racially derogatory statements that were captured on the video, Ford said.
After the victim fell to the ground, the assailants kicked him multiple times in the head, knocked out several teeth and left shoe impressions on his skin, Ford said.
The victim was able to get to his feet and escape the onslaught, and will need to undergo dental surgery.
The teens who were arrested were identified from the video, which was discovered by a Palmdale sheriff's deputy and has been retained for evidence. Authorities are not releasing the video.
Police are seeking three more suspects.
An arraignment date has not been set yet.
