Lancashire police have urged two men who they believe witnessed a brawl on Friargate, Preston to get in touch.
A group of teenagers was seen fighting with a group of men before running off across the city centre at around 4.25pm on Saturday, June, 6.
Police arrested two 16-year-old boys and a 14-year-old boy from Preston in connection with the incident earlier this week.
The three teens were arrested on suspicion of committing a public order offence and they have been bailed until August, 3.
It is thought that nobody was seriously injured but police believe a weapon may have been used.
And now the police want to speak to two men about the incident.
DC Paul Taylor of Preston Police said: “We have an image of two men whom we are keen to trace and speak. We believe that they were witnesses to what happened and may hold important information about the incident and those people involved.”
Anyone with information about the incident or about the offenders can contact Preston Police on 101 quoting log reference 977 of 6th June.
Alternatively, they can contact Crimestoppers anonymously on 0800 555 111 or online at Crimestoppers-uk.org. No personal details are taken, information is not traced or recorded and you will not go to court.
