Senior officers have turned down a request from West Ham to police their stadium on matchdays due to a lack of radio signal.
The Hammers moved into the London Stadium this season but there has been crowd trouble at the games against Bournemouth and Watford.
West Ham have subsequently requested a police presence inside the stadium to help stewards, who have struggled to contain the problem.
However, the deputy assistant commissioner of the Metropolitan Police, Peter Terry, has confirmed the request has been turned down as the £700million ground does not have a “satisfactory” radio system.
Terry said: “Until there is comprehensive radio coverage officers will not be routinely deployed within it.
“This issue was highlighted to the stadium operators in October 2014 and the Metropolitan Police Service (MPS) has been in negotiation with stadium operators regarding the provision of Airwave radio inside the stadium.
“During this time, the MPS had spoken to the stadium operators several times to highlight the consequences of not installing such a system.
“The MPS is not able to provide Special Policing Services at this time as it would normally, as there is no satisfactory radio system across the ground.”
