West Ham will issue life bans to those who found responsible for attacking the Manchester United’s bus before Tuesday’s game at Upton Park.

The tragic incident has happened before the match between West Ham United and Manchester United on Tuesday at Upton Park involving some of West Ham’s supporters pelted missiles on Manchester’s bus before the match. A window on the bus was smashed and the kick-off delayed by 45 minutes as a result of the trouble.
Manchester United’s goal keeper David de Gea was also targeted during the game as a bottle thrown in his direction after he celebrated his team’s equalizer (1-1) and a pitch invader ran on to taunt him towards the end of West Ham’s thrilling 3-2 win.
The game was reported to be West Ham United’s final game at Upton Park before moving to the Olympic Stadium.
“We are aware that there were some supporters outside the Boleyn Ground who didn’t act in an appropriate way,” a club statement read.
“We will work closely with both clubs and the Metropolitan Police to fully investigate these matters,” it added.
West Ham vice-chairman Karren Brady used Twitter to condemn the attack on Manchester United’s bus.
Those who chose to behave unacceptably will be dealt with in the strongest way possible, with life bans for those guilty of violence 3/3

Their behaviour was unacceptable &won’t be stood for. But my overriding memory will not be of them but of a fitting farewell to the Boleyn — Lady Brady (@karren_brady) May 11, 2016
