Fleetwood manager Joey Barton says he "emphatically" denies all allegations made against him following Saturday's defeat at Barnsley.
Barnsley striker Cauley Woodrow tweeted that Barton allegedly confronted Reds manager Daniel Stendel after the game.
South Yorkshire Police are investigating an incident in the tunnel at Oakwell have bailed a man who was arrested on suspicion of racially aggravated offences.
"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.
Chief executive Shaun Harvey has promised the EFL will help investigate an alleged incident involving Fleetwood manager Joey Barton at Barnsley.
Barton is said to have confronted Reds boss Daniel Stendel in the tunnel following Saturday's game, which ended in a 4-2 victory for the home side at Oakwell, and South Yorkshire Police are investigating.
Harvey told BBC Radio 5 Live's Sportsweek programme: "As an off-the-field matter the tunnel is still in the domain of the referee but we will work closely with everybody to ensure it's not a case of who deals with the matter but actually the matter is dealt with properly.
"The police investigation is ongoing so we need to leave the details for them to deal with."
A South Yorkshire Police spokesman said: "We are aware of something that has taken place in the tunnel after the game and we are investigating."
Police were filmed stopping Barton from leaving Oakwell after the Sky Bet League One game.
Harvey added: "I was stunned when I heard. We have all heard of tunnel fracas as players have left the pitch. It's the first instance I've heard, described as it has been, by those who witnessed it.
"It's disappointing and it comes on the back of a number of challenges which have come to the surface for football to deal with."
Joey Barton will face the media for the first time as a manager on Monday when he is unveiled as manager of Fleetwood.
The former Burnley midfielder's 13-month ban for betting on football matches ended on Saturday, allowing him to finally take up the role as boss of the Sky Bet League One club.
Barton was announced as John Sheridan's successor in April on a three-year deal but was unable to start work until his suspension from football activities was served.
After his ban finished Barton wrote on Instagram: "Delighted to take over as Head Coach of @ftfcofficial (Fleetwood Town).
"Really looking forward to joining a forward thinking football club. #OnwardsTogether."
Fleetwood welcomed Barton by posting a picture of the once-capped England midfielder holding a club scarf above his head on their official website.
"The vastly-experienced 35-year-old, who excelled during his top-flight playing career with the likes of Manchester City, Queens Park Rangers and most recently Burnley, will take charge of the club's first team this summer with pre-season starting on Monday 18th June," said a club statement.
Barton was banned by the Football Association in April 2017 for placing 1,260 bets on football matches over the course of 10 years.
The ban was then reduced by five months following an appeal, allowing Barton to start his managerial career ahead of the 2018-19 season.
