'Unacceptable': West Ham vows life bans for fans behind Manchester United bus attack

London, United Kingdom:  West Ham United on Wednesday vowed to ban for life any fans found to have taken part in an attack on the Manchester United team bus before their key Premier League game.

The attacked marred West Ham’s 3-2 win over the English giants in the final match at the London club’s Boleyn Ground on Tuesday. The match was delayed for 45 minutes as police in riot gear cleared troublemakers who hurled bottles and cans at the bus while Manchester players cowered on the floor. “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,” the club said in a statement.

Three men were arrested during the game, including a 20-year-old on suspicion of affray and two men aged 47 and 18 for rushing onto the pitch. Police are scouring closed circuit television images of the troubles and have appealed for witnesses. West Ham co-chairman David Sullivan had initially blamed United for the delay to kick-off, saying they should have arrived earlier at the ground. But vice-chairman Karren Brady later condemned the bus attack. “I, the board and everyone at West Ham United totally condemn the unacceptable behaviour we saw outside the ground last night,” Brady wrote on Twitter. “West Ham is a family Club and the vast majority of fans attended Tuesday’s Final Game to respectfully say Farewell Boleyn. “Those who chose to behave unacceptably will be dealt with in the strongest way possible, with life bans for those guilty of violence. “The events in the stadium last night were incredible and it would be a shame if the actions of a mindless few outside overshadowed them. “Their behaviour was unacceptable and won’t be stood for. But my overriding memory will not be of them but of a fitting farewell to the Boleyn.” Watch the video of the bus attack below:
