At around 3.43am on Sunday the victims, three men in their twenties, were walking on George Street when they were victims of verbal homophobic abuse from a group of men, which escalated into the suspects whipping and hitting the victims with belts.
One victim required hospital treatment after receiving a laceration to his forehead. He has since been discharged.
The two other victims received injuries to their head, stomach and arms but did not require hospital treatment.
An 18-year-old man from Kidlington was arrested on suspicion of assault and affray and released on bail.
Thames Valley Police is appealing for information.
Investigating officer PC Eleanor Middlemass said: “We are appealing to anyone who may have seen the men on George Street on Sunday morning, or anyone with footage, whether that be from CCTV, dashcam or doorbell camera to contact the force.
“The easiest way to contact the force is via our website or by calling 101 or online, quoting investigation reference 43210422073.”
