The Football Association have charged West Ham with failing to control their fans after the shameful scenes that marred Burnley's 3-0 win at the London Stadium in March.
There were mass protests by fans against West Ham owners David Sullivan and David Gold during the match, which led to five supporters invading the pitch as stewards struggled to contain the demonstrators.
In extraordinary scenes, captain Mark Noble wrestled one pitch invader to the turf while another held aloft one of the corner flags as players looked on stunned.
Sullivan and Gold were escorted by security away from their seats for their own safety amid the toxic atmosphere, with missiles hurled at the pair. Sullivan was hit in the face by a coin but saved from injury by his glasses. The Metropolitan Police confirmed that there had been two allegations of assault during the game.
The club took steps to avoid any repeat of the ugly scenes, increasing police and security personnel presence for subsequent matches. Additional security gates were also installed to limit fans' movements around the stadium.
West Ham also said lifetime bans were issued to the pitch invaders and those who threw coins.
It has, however, taken the FA more than three months to announce that West Ham will be punished.
A statement released on Wednesday read: 'West Ham United FC has been charged for failing to ensure that its spectators conducted themselves in an orderly fashion and that no spectators or unauthorised persons encroached onto the pitch during the Premier League match against Burnley FC on Saturday 10 March.
'The club has until Thursday 5 July to respond.'
