Calls for culprits to be banned for life
The Football Association 'strongly expect' all culprits involved in the violence which marred West Ham United's Carling Cup tie with Millwall to be banned from football for life.
Prior to the second round tie at Upton Park, a man was stabbed and trouble flared between opposing supporters in what police labelled "large-scale" trouble.
There were also several pitch invasions in the latter stages of the game, which West Ham won 3-1 after extra time.
Hundreds of fans were involved in the disorder which police said was caused by people without tickets to the tie who had planned to start trouble.
Police said later that the victim of the stabbing was a 44-year-old man who was in a stable condition in hospital.
A Football Association spokesperson said: "We absolutely condemn all of the disorder that has occurred at Upton Park this evening both inside and outside of the ground.
"We will be working with all parties, including the police and clubs, to establish the facts surrounding tonight's events.
"We strongly expect all culprits to be banned from football for life. They have no place in our game."
As the final whistle blew at Upton Park hundreds of fans invaded the pitch. Police and stewards battled with fans in an attempt to remove them from the field of play.
As thousands of fans flooded from the ground, police closed several roads surrounding Upton Park and ushered them towards the tube station.
Around 200 officers in riot gear, backed up by at least 20 mounted officers, patrolled outside the station.
Rubbish, shards of glass and beer cans were strewn across Green Street and bricks could be seen in rubbish bins.
The Metropolitan Police said tonight they had no reports of any officers being injured during the violence.
