People were sought after violence and racist chanting

Police arrested the 38 men and one woman between Thursday and Sunday over the violence at the Stoke City v Birmingham City game in February.

All 39, aged from 14 to 56, have been released on police bail and are due before magistrates in April and May.

Staffordshire Police said it was one of the largest football-related operations in recent years.

Disorder like that witnessed in and around the stadium a month ago has no place in our community Det Sgt Steve Parker

Seven of those arrested are from the West Midlands area. The other 32 are from Stoke-on-Trent or North Staffordshire.

Detectives had earlier released a number of CCTV still images depicting football fans they wanted to speak to following the disorder.

Det Sgt Steve Parker, from Staffordshire Police, said: "This has been the largest football disorder enquiry in Staffordshire for many years.

"The disorder in February was a set-back to the fantastic work achieved by working closely with fans and the football clubs.

"Disorder like that witnessed in and around the stadium a month ago has no place in our community or our football stadiums."
