Russian footballers Aleksandr Kokorin and Pavel Mamaev are being investigated following a reported attack on a trade ministry official in Moscow on Monday.
According to the BBC, Denis Pak was left in need of medical treatment after Kokorin and Mamaev - who play for Zenit St Petersburg and Krasnodar, respectively - assaulted him at a cafe.
Russia's interior ministry are believed to have opened an investigation into the matter, while both the aforementioned clubs are seeking to break ties with the accused players.
