Tottenham Hotspur full-back Benoit Assou-Ekotto is being investigated by police following an allegation of assault.
The Cameroon international is alleged to have clashed with a fan at the end of Spurs' 1-0 defeat by Wolves at White Hart Lane on Saturday.
Assou-Ekotto had to be led away by Tottenham's assistant manager Joe Jordan following the confrontation with the supporter.
Spurs confirmed on Saturday evening that the club were looking into the incident and police are also now conducting their own investigation.
A police spokesperson said: "The police are investigating an allegation of assault following yesterday's Spurs v Wolves Premier League match at White Hart Lane.
"There have been no arrests."
It is understood the allegation came from the supporter, who gave his version of events to security officials after the incident, as did Jordan.
Spurs are also investigating the matter and may look at CCTV footage, as the clash was not caught on camera by broadcasters covering the match.
Harry Redknapp's men were jeered off after the defeat by Wolves that dented their hopes of maintaining a challenge for a UEFA Champions League position this season.
