A number of Celtic fans have been ambushed by Lazio supporters after their Europa League clash, according to reports online.

The Evening Times reports that around 20 people, thought to be Lazio fans, gave chase after a shuttle bus carrying Celtic supporters from the stadium broken down.

Reports on social media suggest those on board the bus were told to walk after the breakdown, where they were then ambushed by Lazio fans.

A BBC reporter on the scene said it is unclear if there are any serious injuries.

"About 20 Lazio fans sprinted from the dark and ambushed the group at the river. Got away safe, not sure about others."

Two of the 8,000 Celtic supporters who travelled to Rome had been stabbed on Wednesday night and security was tight in and around the stadium.

Rab Robertson wrote: “Fair squad of us ambushed, weans the lot, completely co-ordinated, hopefully all safe”, while Thomas Lunday tweeted: “Not enough buses to take everyone back to the city, so rest of the fans had to walk a couple miles further on that’s when they where ambushed by casuals.”

The Celtic fan liaison officer advised fans to “keep a low profile” as they returned from the game.

He tweeted: “Wee update for fans in Rome, don’t walk back to town, get taxis or shuttle buses back to the city and keep a low profile.”
