“With regards to the alleged incident on Saturday following our game against Barnsley, I emphatically deny all the allegations made,” Barton posted on Twitter.

“Given this matter has not been formally closed, it would be inappropriate for me to make any further comment.”

Woodrow, whose tweet was later deleted, claimed the incident left German coach Stendel with “blood pouring from his face”.

South Yorkshire Police are keen to gather any available video footage of the event.

“A man arrested on suspicion of racially aggravated public order offence and racially aggravated assault, in connection to an incident at Barnsley Football Club on Saturday 13 April, has been bailed until next month,” read a police statement.

“Officers investigating the incident would be keen to speak to anyone who may have caught the incident on camera or who may have mobile phone footage immediately before or after the incident occurred.”

Barnsley announced on Tuesday that they had lodged formal complaints with both the English Football League and the Football Association over the alleged incident after the match.

Police said inquiries into the incident are ongoing and asked people to refrain from speculation that could potentially harm their investigation.

On Thursday afternoon, Fleetwood revealed details of an “access-all-areas” club documentary which followed Barton’s appointment as head coach in June 2018 and on through pre-season into the new campaign.

Film crews have been granted access to Barton’s team talks as well as board meetings to look at “all aspects of the day-to-day workings of the English Football League club to provide an unprecedented insight for viewers”.

Fleetwood chairman Andy Pilley said: “The level of access that has been given to the film crews to Joe, the players and his staff I believe is unprecedented. The production crew are embedded at the very heart of the club.”

Press Association Sport understands the timing of the announcement is completely unrelated to the alleged incident at Oakwell, with the planning for the press release surrounding the ongoing project having been made months in advance.
