A police officer required emergency medical treatment after being struck in the head with a traffic cone thrown by a group of football fans.
The officer sustained “serious injuries” following the incident in the lead up to Hearts’ Europa League qualifying tie with Swiss side FC Zurich on Thursday, August 25.
It is understood a group of supporters were being escorted to the stadium in the Gorgie area of Edinburgh when the object was thrown on McLeod Street.
Nearby medical personnel attended to the officer while the rest of the fans were ushered towards the ground.
Police have now launched an appeal to trace the person responsible and are asking anyone who may have taken video footage before the match to pass the film on to investigators.
Zurich won the game 1-0 to advance to the group stages of the competition.
Detective constable Andy Lambert, of Gayfield CID, said: “An officer was injured as a result of this incident so we are appealing for anyone who was in the area and witnessed what happened to get in touch.
“I would also encourage anyone who may have video footage of the incident to contact us.”
DC Lambert added: “Anyone with information should contact police via 101, quoting incident 2449 of 25 August. Alternatively, Crimestoppers can be contacted anonymously on 0800 555 111.”
