Police have issued CCTV images of two men, believed to be from Huddersfield, over a brawl outside a Bradford nightclub.
Detectives say the men, one of whom has a distinctive tattoo around his neck, may have vital information.
Five people were injured in Sackville Street, near Club C’s, in the early hours of Monday May 26.
A number of people, including a Huddersfield man, have already been arrested and charged.
Police have released the images and say they want to hear from the men pictured “at the earliest opportunity.”
One of them is described as having a tattoo in the form of written words around the sides and back of his neck.
Det Sgt Stuart Lyons, of Bradford District CID, said: “We are urging these people to come forward and tell us what they know about the disorder in Sackville Street, as they may have information which could be vital to our investigation.
“Similarly, we would also ask for anyone who might be able to identify these people, or anyone who might have further information about the incident, to contact police on 101 or anonymously to Crimestoppers on 0800 555111.”
The nightclub has since closed voluntarily after police applied for its licence to be revoked. It was said to be a “nucleus” for violence.
The Huddersfield man charged is Marcus Kaye, 20, of North Carr, Rawthorpe, who has been accused of violent disorder, wounding and robbery.
In unrelated investigations, police would like to speak to the people pictured in the image gallery below. The people pictured in the images may be witnesses as well as suspects. If you recognise anyone, contact police on 101 quoting the reference number on the image caption.
