West Ham has promised to issue lifetime bans to unruly fans after Manchester United's team bus was attacked by supporters prior to kickoff.

Tuesday's stunning 3-2 Premier League victory and farewell to Upton Park was overshadowed as West Ham fans pelted United's coach with bottles on its approach to the stadium.

The pregame scenes and United's late arrival forced kickoff to be delayed by 45 minutes. West Ham is now working with police to as they attempt to identify those involved in the attack.

"It was an extraordinary night full of extraordinary moments in front of extraordinary fans. 99 percent of whom behaved impeccably and were a credit to the club," a statement read. "We have already had thousands of tweets and emails from fans to say how proud they were to be a part of such a special evening in West Ham's history.
 
"However, we are aware that there were some supporters outside the Boleyn Ground who didn't act in an appropriate way when the Manchester United team bus was damaged. That was not acceptable and we will work with the police to identify those responsible and ban them for life."

Winston Reid was the hero for sixth-placed West Ham, which played its final game at Upton Park before making the move to the Olympic Stadium next season.

Reid netted the 80th-minute winner after Michail Antonio had equalized four minutes earlier, cancelling out a second-half brace from United star Anthony Martial.

Diafra Sakho had opened the scoring for West Ham 10 minutes into the game.
