Six people have been arrested following a police operation during the Millwall vs West Ham match in south-east London, with officers dealing with a number of incidents around the fixture.
The arrests came as police stepped up their presence for the highly anticipated meeting between the two clubs, with supporters from both sides travelling to the area for the game.
According to the police, the offences recorded during the operation included tailgating, assault on a police officer, and entering or attempting to enter the stadium while intoxicated.
The arrests highlight the increased security measures that were in place around the match, with officers working to prevent incidents inside and outside the stadium.
The fixture was expected to attract significant attention given the rivalry between the two clubs, and police were prepared for potential disorder before, during and after the final whistle.

While the majority of supporters attended the game without incident, the arrests demonstrate the challenges faced by authorities when managing large crowds at high-profile football matches.
Police operations around fixtures of this nature are designed to protect supporters, players, staff and officers while ensuring that those attending can watch the match safely.
The six individuals arrested are expected to face further enquiries as police continue to establish the full circumstances surrounding each incident.
Authorities have continued to urge supporters to behave responsibly and follow stadium regulations, particularly during fixtures where tensions can run high.
