Manchester United’s team coach was pelted with dozens of bottles as it arrived at Upton Park tonight for West Ham’s last ever game at the stadium.
Man U and England captain Wayne Rooney, who was on board, said the coach had been “smashed up” as the shaken players finally arrived at the stadium.
Scotland Yard said a police officer and a member of the public were injured when trouble flared.
Video footage shows dozens of glass bottles being hurled at the coach as it made its way slowly through the streets crowded with West Ham fans.
Officials put the kick-off of the match back 45 minutes from 7.45pm to 8.30pm.
Rooney said: “It wasn’t nice. The coach got smashed up, but we are here now.
“I’m sure you’ll see the images.”
He added: “It’s not for me to say, but it was disappointing of course.
“It’s a big night for West Ham, but I’m sure West Ham as a club will be disappointed with what the fans have done.”
A Scotland Yard spokesman said: “We are aware that a number of items were thrown towards Manchester United’s coach this evening.
“One officer and a member of the public sustained minor injuries.
“There have been no arrests. An appropriate policing plan in place.”
West Ham’s joint chairman David Sullivan said it was “disappointing” that Manchester United had not arrived at the ground much earlier.
