West Ham and the London Stadium say 200 people face football banning orders following the violence during Wednesday night's game against Chelsea.
Police made seven arrests after skirmishes broke out towards the end of the stadium's first London derby, when West Ham won 2-1.
Police and stewards battled to maintain segregation behind the goal being defended by West Ham as coins, seats and other objects appeared to be thrown between rival supporters.
The Hammers and Chelsea condemned the unsavoury scenes which are now under investigation by the Football Association -- and swift and decisive action is being taken after the CCTV footage was pored over on Thursday.
