The word "England" was inscribed in red across the chest of ex-Spartak Moscow player Fyodor Cherenkov in the vicinity of the Spartak Stadium on Tuesday evening.
An investigation has now been launched and one individual has been identified as a potential culprit, but his or her nationality has not been revealed.
