A man has been arrested following an alleged altercation between Fleetwood boss Joey Barton and Barnsley head coach Daniel Stendel at Oakwell.
The man attended a police station on Wednesday where he was arrested on suspicion of a racially aggravated public order offence and racially aggravated assault.
He remains in custody for questioning.
Barnsley complained to the FA and the EFL about the incident in the tunnel after Saturday’s League One game.
South Yorkshire Police, which earlier appealed for witnesses, said inquiries were ongoing.
