Three men who were arrested in connection with crowd disturbances at Saturday's Premier League game between West Ham and Middlesbrough have been bailed.
Two were arrested on suspicion of affray and the third on suspicion of assaulting a police officer.
Supporters were seen confronting each other inside West Ham's new London Stadium and fighting outside, while footage of violence appeared on social media on Saturday evening.
Police said no injuries were reported either before or during the 1-1 draw and said there had been "a small minority intent on causing disruption."
A Metropolitan Police statement, released on Sunday, said: "Three men have been bailed pending further enquiries following their arrests in connection with a disturbance outside the ground following the West Ham and Middlesbrough match on Saturday 1 October.
