Celtic goalkeeper Artur Boruc could face court action over allegations that he taunted rival fans by blessing himself during an Old Firm match.
The Polish international is the subject of a report to the procurator fiscal following a six-month investigation.
A number of complaints were received by police after the Scottish Premier League match at Ibrox, Glasgow, against Rangers on February 12, which Celtic went on to win 1-0.
Boruc, 26, is said to have angered a section of the home support after allegedly making the religious gesture.
A Crown Office spokesman said: “A report has been received and it is being considered.”
A Strathclyde Police spokeswoman said: “The circumstances surrounding the alleged actions of a football player during the Old Firm match at Ibrox on February 12 2006 have been investigated and referred to the procurator fiscal at Glasgow.”
The Polish goalkeeper, who played during this year’s World Cup in Germany, signed for Celtic from Legia Warsaw in July last year.
