West Ham United’s farewell party turned sour when Manchester United’s team bus got attacked by bottle-throwing home fans after it got stuck in traffic.

Huge crowds, many without tickets, had congregated outside the stadium for the sell-out Premier League clash, West Ham’s final home game before moving to the 60,000-seat Olympic Stadium after 112 years at Upton Park.

Several windows on the coach were damaged during the chaos and policemen with riot shields moved in to quell the trouble.

The Football Association also announced that it would launch a full investigation, including an incident where objects were thrown at United goalkeeper David de Gea during the game.

“The FA strongly condemns the unsavory incidents this evening,”

said in a statement.
