Tottenham Hotspur have been criticised by the Football Supporters Federation and a number of human rights groups over their decision to give stewards at White Hart Lane head-mounted cameras in order to keep an eye on the behaviour of fans.

The North London side announced yesterday that the headcams would be worn during last night's Premier League match against Chelsea in order to catch any discriminatory behaviour in the crowd.

"Fans often get upset when police film them," FSF chief Malcolm Clark told BBC Sport. "It's unfortunate Spurs use cameras on stewards without engaging in a wider discussion on how they will be used.

"There's the potential for tensions if fans are filmed by stewards without, as they see it, a good reason.

"We have questions over when it will be used. At all games? Or just some games? And what instructions will be given to stewards about when to film? Will it be under particular circumstances or all circumstances? If they want FSF support then this isn't the way to go about it."

Spurs are believed to have agreed to consult with the Federation over issues with the system.
