Investigating officer PC William Matthews, based at Cowley Police Station, said: “This was a violent assault, which appears to have been unprovoked.

“One of the three victims sustained serious facial fractures which will require surgery to rectify.

“The assault happened in the early hours of Saturday morning, and I am releasing three images of people who may have vital information that may assist this investigation.

“If you recognise any of the men pictured, or you believe one of them is you, please get in touch with Thames Valley Police.

“You can contact us online via our website, or by calling 101, quoting reference 43240480264.

“Witnesses to the incident can also call the independent charity Crimestoppers anonymously on 0800 555 111 if you wish to remain anonymous.”

The city centre nightclub recently had a bid refused by Oxford City Council to extend its opening hours to 3am from Sunday to Saturday.
