More Scottish Cup Final Fan Images
Police have released images of 12 more fans they want to trace in connection with the crowd trouble and pitch invasion at the end of the Scottish Cup final.
The match at Hampden Park on May 21 was disrupted when fans invaded the pitch after Hibernian's 3-2 win over Rangers, the Edinburgh side's first Scottish Cup win in more than a century.
Hibs supporters flooded the pitch after their side's dramatic last-minute win, with Rangers fans also making it past stewards and on to the turf before mounted officers restored order.
Police have arrested 86 people to date in the investigation into alleged violence, disorder and vandalism, and have now released photos of 12 supporters they believe may be able to help them with their inquiries.
The latest release follows previous police appeals for help in identifying fans.
A police statement said: "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 or the dedicated mailbox address: Scottishcupfinalpitchinvasion@scotland.pnn.police.uk or alternatively Crimestoppers can be contacted on 0800 555 111, where anonymity can be maintained.''
The Scottish Football Association has said neither club will face punishment for the crowd trouble in line with the governing body's disciplinary rules.
An independent report commissioned by the SFA said the Scottish Government should consider making it a criminal offence to run on to a football pitch.
Jim McCafferty used to work at Celtic, Hibs and Falkirk.
Michelle Thomson says her attacker was known to her.
A woman who has been charged with driving six times over the legal drink-drive limit had two children in her car, police have said.
