After police dawn raids this morning led to the arrests of three people wanted in connection with violence at an FA Cup match between Millwall and Wigan at Wembley, a further man has handed himself in.
The 34-year-old was arrested on suspicion of violent disorder at a south London police station.
We have had an excellent response from the public, and we believe that we have identified everyone in those ten images previously released.
Some have since handed themselves in to police, and to date, we have arrested 27 people on this inquiry.
