The match ended in controversy with angry scenes amid allegations that visiting player Ondrej Kudela made a racist comment to Rangers midfielder Glen Kamara during the closing stages of the game.
The Czech club denied the allegation – detailed by Finnish international Kamara via his lawyer’s statement on Friday evening – and countered with claims of a post-match bust-up in the tunnel area within Ibrox.
Police Scotland initially said no complaint had been received following the encounter but after Slavia detailed their report process with the Czech embassy in London – the force has confirmed an investigation has been launched into the alleged incident.
A spokesperson said: "We have received a report of an assault following the match between Rangers and Slavia Prague at Ibrox on Thursday, 18 March, 2021. Officers are liaising with both teams and an investigation is under way."
Slavia progressed in the Europa League with a 2-0 win at Ibrox taking them through to a quarter final with Arsenal, but the match has been overshadowed by Kamara’s racism allegations – and further online slurs aimed at the midfielder and his Rangers team-mate Kemar Roofe.
The Czech club’s chairman Jaroslav Tvrdik criticised a racist banner aimed at Kamara held up by a group of fans in an image posted online, saying he was “extremely ashamed” by the photo and while Slavia have denied Kamara’s claims of racism on the pitch, they have vowed to respect the UEFA investigation into the incident which is now underway.
