The Sunderland boss, who has since apologised, took exception to being asked if he was under more pressure with club chairman Ellis Short in the stands for his side's 0-0 draw with Burnley last month.
BBC reporter Vicki Sparks was then told by Moyes: 'It was getting a wee bit naughty at the end there so just watch yourself. You still might get a slap even though you're a woman.' He then went one step further and added: 'Careful the next time you come in.'
During the interview Moyes had abruptly told Sparks he was not under any pressure at all but when he thought his television duties were done, his manner changed.
Though Sparks appeared to awkwardly laugh off the remarks, Moyes seemed as though he was not joking.
