Ticketless fans breached security and gained access into Wembley Stadium ahead of the Euro 2020 final between England and Italy.
Wembley officials confirmed a “small group of people” entered the ground after footage earlier showed crowds of supporters making a mad dash to get inside before the 8pm kick-off.
A Wembley Stadium spokesperson said: “There was a breach of security and a small group of people got into the stadium.
“We are now working closely with stadium stewards and security to remove these people. Anyone inside the stadium without a ticket will be instantly ejected.”
The Metropolitan Police said they supported the security teams at Wembley Stadium.
“Earlier this afternoon there was a breach of security at Wembley Stadium, which resulted in a small number of people getting into the stadium without a ticket,” Metropolitan Police said.
“Officers worked closely with security officials to prevent any further breaches. We will also support action by Wembley Stadium officials to identify those without tickets and eject them.”
Wembley officials had earlier denied fans had gained access to the ground without tickets.
Huge crowds of people gathered outside Wembley and across London throughout the day, prompting police to urge anyone without tickets not to travel to the stadium.
England are playing in a men’s major tournament final for the first time since the 1966 World Cup.
