The Manchester City fan at the centre of a racism storm after yesterday's derby match is a 40-year-old family man, MailOnline can reveal.
Anthony Burke from Manchester was filmed appearing to make racist gestures and monkey noises at midfielder Fred during the game.
The father appears to have served in Northern Ireland with the British Army and according to his social media is a civil engineering manager at Kier Group.
Burke's ex-partner has told Mailonline he was arrested this morning by police.
Amy, of Wythenshawe, Manchester said: 'He is with the police - he has been arrested.
'He was arrested this morning. He doesn't live with me. It's horrible - I have had death threats and my kids.
'I have been in tears.
'I am really surprised - this is not like him - his family are black.
'I keep watching the footage back and I can't say whether he's done it or not.
'Has he done it or hasn't he done it?
'I just can't say and I haven't spoken to him.'
She added: 'It's amazing how you can get famous for the wrong thing.'
Kier Group plc tweeted this morning: 'We're aware of a video circulating on social media. We take allegations and instances of racism very seriously and are currently investigating potential links between the individual involved and Kier.'
