Former soccer coach Ron Atkinson has been carpeted by bosses of U.K. reality Tv show Celebrity Big Brother for making an inappropriate remark towards a female contestant.

The ex-Manchester United manager saw his reputation plummet in 2004 after he was caught describing a black football player as a "f**king lazy n**ger" during an unguarded moment when he thought a Tv studio mic was switched off.

He was forced to resign from his role as a pundit with British network ITv, but now Atkinson - known affectionately as 'Big Ron' - has risked attracting accusations of racism once again after making a remark apparently referring to Muslim suicide bombers.

The incident came on Sunday (25Aug13) when a fellow housemate, named Danielle Marr, wrapped a sweater around her head which then resembled a hijab headscarf.

Atkinson stunned viewers by asking, "You're not carrying a bomb with you?"

Shortly after the incident, Atkinson was taken to the show's 'Diary Room' where producers warned him he would be fired from the programme if he makes any more inappropriate remarks.

Following the rebuke, Atkinson told viewers, "I came in determined not to upset anybody. One of my prime tasks was to make sure I didn't upset, so I'm very aware of what I am saying."
