Police confirmed that two West Ham supporters were formally cautioned by officers after making "racially-aggravated gestures" during yesterday's match.
The pair of fans were arrested during the game and accepted the police cautions, Scotland Yard said.
One of those was a Hammers season ticket holder who has since been banned.
Tottenham Hotspur have confirmed that five supporters were arrested during Sunday's match at White Hart Lane outside of the stadium for unrelated incidents and two more were cautioned for racially aggravated gesturing inside the ground.
One of those fans has since been identified as a season ticket holder and has, this afternoon, been sent a letter containing a banning order from the club.
Any other individuals identified can expect a similar swift and robust response.
