Celtic fans have staged a protest at the potential appointment of Bernard Higgins to a senior security role at the club.
Supporters unveiled a banner and fell silent for a period of Saturday's clash with Livingston amid rumours Police Scotland 's assistant chief constable is being lined for a job at Parkhead.
A statement signed by several fan groups on Friday announced the intention to stay quiet during the first 30 minutes of the Premiership match.
There was no singing or chanting from the standing section inside Celtic Park after they unveiled a banner declaring Higgins was not welcome at the club.
The banner carried a photograph of the officer with the words: "His evil eyes have no place in Paradise"
The statement, endorsed by the Green Brigade, North Curve Celtic, Bhoys, Celtic Shared and the Celtic Trust, said Higgins had a key role in utilising and defending the now revoked Offensive Behaviour at Football Act.
Fan groups accused the Celtic board of creating a sideshow just as Ange Postecoglou 's team are hitting top form.
The statement said: “We have recently been made aware that Bernard Higgins of Police Scotland is likely to be appointed to a senior security role at Celtic.
"Higgins played a major part in the vicious implementation of the much-hated Offensive Behaviour at Football and Threatening Communications (Scotland) and passionately defended the legislation within the Scottish Parliament.
"As assistant Chief Constable, Higgins’ remit involved strategic decisions on the policing of football across Scotland."
The statement continued: "On Saturday, we will remain silent for the first 30 minutes of the match. This will make clear to the Celtic board the level of opposition to his appointment.
"We understand that our stadium is renowned for the atmosphere created within it, and we desperately want to provide that backing to the players, however we kindly ask those who disapprove of this potential appointment to join us in this protest.
"It is regrettable that once again the Celtic board should create a sideshow which detracts positive support for the team, particularly at a time when Ange Postecoglou and the team are starting to deliver encouraging performances and results.
"We call on the board to do the sensible thing and not appoint Bernard Higgins to this role.
"Otherwise, we will continue to campaign against both him and those responsible for hiring him."
Celtic have been approached for comment.
Police Scotland said Higgins was concentrating on his current role in policing Cop26.
