The footage shows a girl being punched and kicked, before being thrown on the ground and further attacked by four young women.
The assault goes on for 40 seconds and the girl appears to be unconscious during a portion of the attack.
“Police located the alleged offenders early this morning, who are known to the victim,” Gillespie said.
The Herald asked police why only three people have been arrested when the video showed four people involved in the attack.
“Inquiries are still ongoing and further charges can’t be ruled out,” a police spokesperson said.
