West Ham co-owner David Sullivan has played down the crowd disturbances during Saturday's home match with Middlesbrough, saying reports on the trouble have been "sensationalised.''
Supporters were seen confronting each other inside London Stadium and then fighting outside, while footage of violence appeared on social media on Saturday evening.
Three men were arrested in connection with the incidents and bailed pending further inquiries. Two of the three were arrested on suspicion of affray and the third on suspicion of assaulting a police officer. Police said no injuries were reported during or before the 1-1 Premier League draw and blamed ''a small minority intent on causing disruption.
