Enhanced security for West Ham v Chelsea
Supporters that attend the West Ham v Chelsea fixture in the EFL Cup will face enhanced security checks, an alcohol ban and a "robust policing plan"
Chelsea have been allocated more than 5,000 tickets for the fourth-round tie, deemed high risk because of a history between fans.
Since West Ham relocated to London Stadium this season, around 23 banning orders have been issued, alongisde a number of arrests happening outside of the ground.
For the visit of Chelsea, fans should expect an "enhanced body search policy" at the turnstile, while no alcohol will be sold before the match from mobile venders outside the stadium.
A spokesperson for partners in the stadium - West Ham, E20 Stadium LLP and London Stadium 185 - said "significant resources" had been applied to the fixture with a "robust policing plan in place".
Until now, the Metropolitan Police have not deployed officers inside the stadium because the radio system emergency services use to communicate will not be operational until 2017.
But the statement added a "tactical solution" was now in place for the "safe deployment of officers in the stadium".
There were clashes outside of the ground after the Premier League draw with Middlesbrough earlier this month, which led to three people getting arrested.
Recent matches have featured increased segregation of opposing fans and more stewards.
