Mr Haslam was attacked in the boardroom at the ground shortly after the final whistle of the 1-0 defeat to Rotherham, which prompted loud protests calling on him to quit the club.

• Man arrested after Mansfield Town owner Haslam assaulted by fan

Police and stewards had formed a barricade to stop angry supporters from storming into the directors area, but it is thought upto three got into the boardroom.

Early on Sunday morning a 45-year-old local man was arrested on suspicion of assault and questioned at Mansfield Police Station.

On Sunday evening Mr Haslam spoke to Chad and confirmed that he had been shaken by the incident, but was not seriously injured.

24 hours earlier he had been taken to King's Mill Hospital, but was later discharged on Saturday evening after receiving treatment to a minor facial injury.

Mr Haslam told Chad: "I am fine. I am shaken, yes, but I am not too bad. Obviously I cannot talk about the incident, but this will have consequences."

When asked if the assault and the fans' hostile reaction at the final whistle would have any bearing on the protracted takeover at the club, he added: "No, not at all. I want to sell, this has not changed that."

Mr Haslam, who said two weeks ago that he would resume takeover discussions with any interested parties once the Stags' League fate was known, told Chad: "I have got to think over the next few days what I want to do. I have always said I wanted to sell for some time now.

"I am not excluding anyone from talking about buying the club, but at the moment it is a question of who is out there."

When Chad pointed out that the controversial John Batchelor insists he is ready to do a deal, Haslam added: "He might be the only one around, who knows?"

"As before, people have got to be able to show what they can do. I know this has been a long saga, but so far people have not been able to fulfill their commitments.

"What I want for the club has always been the same, nothing has changed from that because of Saturday."

And on Monday Batchelor told Chad: "Of course I am still interested, very much so. I have plenty of plans for Mansfield if I can just get control."

Talking about the crucial defeat to Rotherham, which leaves the Stags almost certainly facing non league football next season after 77 years in the Football League, Mr Haslam added: "I am very, very disappointed. A flukey goal has had a major effect.

"At half-time the Rotherham directors said to me we should be happy with the score, but I said I wanted a win.

"At that time we looked okay. But then things went dramatically wrong. Things like that seem to happen in football.

"Their lad was just keeping the ball in play, a high lob and the next second they have scored. It was a fluke.

"I remember a few years ago Sheffield United going down after losing at Chelsea with virtually the last kick. As I said, things like that seem to happen in football. One minute you are okay, the next you are not."
