West Ham's Premier League game with Burnley was interrupted by fans invading the pitch on Saturday.
After the home side fell behind to Ashley Barnes' left-footed 66th-minute strike, two supporters entered the field of play to protest against the club's hierarchy, with West Ham battling against relegation.

Home captain Mark Noble confronted one of the individuals, knocking him to the ground as the atmosphere turned toxic inside the London Stadium.
Stewards arrived at the scene to escort the duo from the field, though trouble continued in the stands.
Referee Lee Mason was also forced to stop the game shortly after when another supporter came on to the pitch, grabbed a corner flag and attempted to plant it in the centre circle.
