Leigh Griffiths has found himself at the centre of a police investigation after the Dundee striker kicked a flare into St Johnstone fans.
The 31-year-old reacted after the visiting support hurled abuse at the on-loan Celtic man by booting the smoke bomb into their section.
It came during the Dark Blues 2-0 Premier Sports Cup quarter final defeat to their Tayside rivals and trophy holders.
Footage emerged on social media after the incident and a police spokesperson said no injuries or complaints had been reported - but that they have launched an investigation.
The spokesperson said: "We are aware of an incident involving a small number of smoke devices at Dens Park, during the match between Dundee and St Johnstone Football Clubs on Wednesday, 22 September.
"There were no injuries and no complaints have been made to police at this stage.
"Enquiries into the matter are ongoing.”
Griffiths - on loan at Dens Park from Celtic - is already set to face an SFA hearing over the incident.
St Johnstone won the game thanks to goals from Shaun Rooney and Ali Crawford as they look to hold on to their silverware.
Dundee issued a statement over the “regrettable incident” which read: “Following the opening goal a smoke generator, amongst other items, was thrown onto the park by the visiting supporters. This pyrotechnic ended up back in the stand as Leigh kicked it to remove it from the field of play.”
Griffiths added: “It was regrettable that the pyrotechnic ended up back in the stand as my intention was just to remove it from the pitch.
“Having just lost a goal I was eager to get the match restarted as quickly as possible and I would like to apologise for any distress caused by this action.”
