As a Lincoln vs Luton football fixture looms, Lincolnshire Police are asking residents if they know the pictured trouble maker.
In October last year, a Luton and Lincoln football match was ruined by violence that kicked off in a pub on the High Street.
During the incident, furniture and glasses were thrown, and two women were treated in hospital for injuries sustained by the flying glass.
Since, 21 arrests have been made and 16 men have been charged with offences arising out of the incident.
Out of the arrests, 12 pleaded guilty, and another four will go on trial at Lincoln Crown court in November.
However, the man pictured is still yet to be identified and questioned. He is believed to be a Luton Town supporter.
Officers believe he may or may not attend the Luton match on September 21, but police warn residents to report any sightings of him.
Lincolnshire Police football liaison officer PC Andy Pearson said: “Operation Hartford is a post match investigation into a violent confrontation that took place before the Lincoln City v Luton Town Blue Square Premier League fixture on October 6 last year.
“Lincolnshire Police will continue to be proactive in dealing with any incidents of football related disorder and work closely with Lincoln City Football Club to ensure that the local community remains a safe and welcoming place.”
Contact PC Pearson by calling the non emergency 101 number. Alternatively you can report football disturbances or sightings of this male to Crimestoppers anonymously on 0800 555 111.
