Officers investigating an incident of violent disorder in Osmaston Road in May are appealing for footage.
Police attended the location shortly after 7pm on Thursday 23 May following a report of a fight in the area.
Three men have since been charged with violent disorder and are due to stand trial at court at a later date.
