The Scottish Football Association are investigating another incident involving Celtic striker Leigh Griffiths.

The former Hibernian loanee has already been issued with a notice of complaint by the SFA for singing in public about the administration situation of Edinburgh rivals Heart of Midlothian.

Griffiths was seen singing in a derogatory nature directed at Hearts in a pub before a match recently and is now facing a racism claim after allegedly joining in with Hibees fans who sang a song about former Hearts midfielder Rudi Skacel being 'a refugee'.

It is understood that the SFA will consider the fresh incident as part of the original charge against Griffiths while a Police Scotland spokeswoman told BBC Scotland that an investigation into the matter will now be launched.

Griffiths has already been disciplined by Celtic for the first occurrence but have yet to comment on the latest allegations.
