Tottenham Hotspur fans have defied police warnings not to use the Y-word in chants.
The Metropolitan Police said they would be "on the look out" for football supporters who used the word during today's home game against West Ham at White Hart Lane.
The Spurs supporters chanted "We'll sing what we want" and "Yid Army" at this afternoon's match.
The Met said that as of 5pm, no arrests had yet been made. Officers had been speaking about the issue with fans on their way into the stadium.
