Police have charged more than 30 Sunderland and West Ham fans who are alleged to have been involved in a fight before a Premier League game.
Trouble flared outside Revolution Bar in Sunderland at around 2.15pm on January 12, ahead of the Hammers visit to the Stadium of Light.
Northumbria Police said 10 fans associated with West Ham have now been charged with violent disorder.
They are aged between 18 and 28 and come from St Albans, Peterborough, Romford, Hornchurch, Basildon, Harefield, Bury St Edmunds and Chelmsford.
They are due to appear before Sunderland Magistrates' Court later this month.
A total of 24 Sunderland fans have already been charged following a lengthy investigation by police.
All of those charged have strict bail conditions restricting their attendance at football matches.
