The Metropolitan Police have arrested a 28-year-old man in connection with the attack on the Manchester United team bus before Tuesday's Barclays Premier League clash at West Ham United.
The suspect handed himself in to an East London police station on Friday and was arrested on suspicion of violent disorder. He has been bailed to a date in mid-August, pending further inquiries.
In what was the last-ever match at Upton Park before the Hammers' move to the Olympic Stadium, Man United's team bus was pelted with bottles and objects, causing kickoff to be delayed by 45 minutes.
Met Police commander BJ Harrington said: "Behaviour of the kind we saw before Tuesday's match is totally unacceptable. The vast majority of people were well behaved, but we are looking to deal with a small minority of individuals who committed criminal acts.
"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.
"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."
West Ham scored twice late on to overturn a 2-1 deficit and sign off with a win at their home of 112 years, denting Man United's chances of sneaking into the Premier League's top four in the process.
