Celtic striker Leigh Griffiths has been filmed leading Hibernian fans in a racist chant regarding former Hearts winger Rudi Skacel before the Edinburgh derby.
The 23-year-old, who was a January signing from Wolverhampton Wanderers, has already been fined by the Bhoys and faces SFA disciplinary charges after he was videoed singing a song about Hearts' financial problems.
He was at it again last weekend at the Roseburn Bar, with a mobile phone recording passed to the Daily Mail showing Griffiths start a chorus of a tune which describes Czech Skacel as a "f****** refugee".
Griffiths is in the grey jumper in the video below.
Griffiths spent two years on loan at Hibernian between 2011 and 2013, scoring 31 goals in 66 games.
