Several people were involved in an affray in Luton town centre on Tuesday morning.
Five people were arrested following the disorder in Manchester Street at about 2.40am.
One man suffered serious facial injuries including a broken cheek bone.
Investigation Officer Oliver Kotis said: “Clearly there were a number of people who had been out for the night in the town
when this disorder broke out. Luton town centre is a great place to socialise and we want it to remain a safe environment which everyone can enjoy. We need those people to contact the police and help piece together the background to this incident and help stop this kind of behaviour from reoccurring.”
Two women both aged 23 years, two men aged 18 years and a man aged 30 were arrested in connection with the incident.
The 30-year-old man was taken to hospital for his serious facial injuries.
