West Ham co-chairmen David Gold and David Sullivan say "lessons have been learnt" following the recent crowd trouble at London Stadium, and confirmed a number of stringent security measures will be introduced against Stoke on Saturday.
Clashes between rival supporters marred the Hammers' 2-1 EFL Cup victory over Chelsea on October 26, with stewards struggling to keep fans apart along the walkway of the Sir Trevor Brooking Stand before police in riot gear managed to quell the disorder.
In the wake of the trouble, West Ham announced a new robust plan to prevent any further violence inside their new home and said that they were close to finalising the identification of 200 individuals involved in the crowd disturbances against Chelsea.
The Metropolitan Police confirmed on Friday that officers will be deployed within London Stadium to assist stewards during the match against Stoke, while West Ham say high barriers and a 10 metre sterile area will also be utilised for the first time.
In their programme notes, Gold and Sullivan said: "As a club and board we fully acknowledge the issues and have been working tirelessly to ensure they are eradicated swiftly, effectively and permanently.
"Today (Saturday) we have implemented even more robust measures which we believe will help ensure the safe and friendly family environment we are all working so hard to achieve at London Stadium.
"We have reached an agreement with the Metropolitan Police that they will have a presence in the stadium from the start of the match and will help form the segregation line with our stewards.
"From the outset, police authorities have stated they have been satisfied with all the safety arrangements but we believe a visible police presence inside the stadium from the off will help underline our determination to provide the safest of environments.
"You'll have seen in the media our determination in line with our clear zero tolerance policy to come down hard on those fans who are acting improperly. Thanks to the state-of-the-art CCTV system there will be more than 200 banning orders in place following the scenes against Chelsea.
"It's important to note that at no time were the lines of segregation breached and the actions of the stewards was exemplary but we recognise we have to do even more.
"We have also created more distance between home and away fans and have widened the line of segregation on both sides of the lower tier where away fans are housed. We believe this was a necessary measure to further enhance the safety of fans.
"Lessons have certainly been learned from the Chelsea game, especially where there were 'pinch points' between fans. Now the segregation line on the lower concourse walkway will be strengthened and widened by implementing high barriers and a 10 metre sterile area.
"Supporters will also be physically segregated as they exit the stadium to prevent clashes outside the turnstiles. This was in place after the Chelsea match and worked well.
"A number of our stewards will also be issued with hand-held video cameras as well as having cameras attached to their armour. Not only will this help with identification but will also act as a clear and visible deterrent.
"All these measures build on those already in place. As a club, we are still working tirelessly because we cannot allow incidents we witnessed against Chelsea in the stands to overshadow the progress we are making on the pitch."
