13 Men Wanted Over Cup Final Disorder
Police investigating the trouble that marred the end of the Scottish Cup final have released pictures of 13 men they want to trace over violence, disorder and vandalism.
So far 38 arrests have been made across Scotland since the match between Hibernian and Rangers on May 21.
Hibernian supporters flooded the Hampden pitch after the Edinburgh side's dramatic 3-2 win, while Rangers fans also made it past stewards and on to the turf before mounted officers restored order.
In the latest police operation, four men were arrested in Glasgow, Renfrewshire and Edinburgh on Thursday for alleged assaults and disorder.
Those previously arrested vary in age from 17 to 50.
Police Scotland have now released 13 images of fans on the pitch at Hampden as they look to make more arrests.
A force spokesman said: ``Police in Glasgow are continuing to investigate acts of violence, disorder and vandalism that took place during the pitch incursion immediately following the final whistle at Hampden Park after the Scottish Cup final on Saturday May 21.
''Police Scotland are releasing images of persons they are keen to trace whom they believe may be able to assist them with their enquiries.
''Anyone with information about the identities of the persons pictured is asked to contact the Incident room at Govan Police Office, Greater Glasgow CID on 0141 532 5457.''
Members of the public can also call Crimestoppers on 0800 555 111, where information can be given anonymously, or use the dedicated email address set up by officers - email@example.com.
Two men accused of attempting to murder two police officers by knocking them over are to stand trial in June.
