The hunt for West Ham fans who threw bottles at police and the Manchester United team bus is under way.
Police would like to speak to four men in connection with the violence at the Boleyn Ground on Tuesday, which was the final game to be played at the stadium.
Three men have already been arrested after the disorder.
Two – one 18, the other 47 – have been bailed to a date in late May after being held for pitch incursions, while a 20-year-old was arrested for affray after being suspected of throwing bottles at police and was bailed until late August.
Commander BJ Harrington, of the Met Public Order Team, said the incidents before the match were “totally unacceptable”, but the “vast majority” of fans were well-behaved.
“We are working closely with both clubs to bring these individuals to justice, and I would urge anyone who recognises the men in these pictures to contact police,” he added.
“This was always going to be a challenging match to police, with passions running high.
“Aware of those challenges, we had more officers on duty than is normal. I am proud of my officers who did a fantastic job in difficult circumstances and played their part in enabling those supporters who respected the occasion to enjoy what was an historic event.”
Anyone with any information should contact the Public Order Team on 020 7275 4569. Alternatively, contact Crimestoppers anonymously on 0800 555 111 or at crimestoppers-uk.org, quoting the image reference number.
