"West Ham United have immediately launched a full and thorough investigation into the incidents which marred the second half of today's match and are committed to taking decisive and appropriate action", the club said in a statement on Saturday night.
West Ham face an obdurate Burnley side who visit the London Stadium with one of the best away records in the country.
Chris Wood's double from the bench was overshadowed by a toxic atmosphere as co-chairmen David Gold and David Sullivan were escorted out of the directors' box for their safety with supporters chanting about the club's leadership.
Premier League officials are likely to question how security at the stadium weren't able to stem the flow of furious fans, with so many pitch invasions in one match a rarity in modern, top-tier football.
Another supporter picked up a corner flag, ran to the centre circle and planted it in the ground. They're just trying to say, "Come on, just get off the pitch".
"There is no place at any level of the game for what happened at the London stadium".

Dedryck Boyata and Stuart Armstrong are both in contention to feature having recovered from a groin and hernia operation, respectively.
Afterwards West Ham manager David Moyes called for the fans to get behind the team. By that stage the action on the pitch had become nearly incidental with fans directing their anger at the club's chiefs.
"We want the supporters behind us, since I've been here they've been really good. There will be no further comment at this time".
West Ham's ageing wing-backs have failed to provide either the energy needed for their role or the experience which should be a given for two players with plenty of history behind them in the game.
"There were a couple of games where I wasn't quite so happy that we didn't do as well as we should have". Sean Dyche has now guided his side to the fabled and of 40 points and will look to build on the confidence which returned to his players throughout last Saturday afternoon.
"We scored a top goal, a great pass from Matt Lowton and a fine lay-off [by Wood]".
"I think it's a tough situation for a player".
