Rangers have contacted Police Scotland after footage emerged of a fan seeming to racially abuse a child before the club's Europa League tie in Macedonia.
The footage, which has been condemned by the club's fans on social media, ends with the man saying "white power" to a group of Macedonian children.
It was apparently filmed before the goalless first qualifying round second leg against Shkupi on Tuesday.
A statement said that Rangers "will take the appropriate steps".
It added: "This kind of behaviour is unacceptable and Rangers have been in touch with Police Scotland."
Police Scotland confirmed that they have brought the footage to the attention of their Macedonian counterparts and are "providing them assistance in their investigation".
Charity Show Racism the Red Card said they "are disgusted by the racism and dehumanisation" in the footage and asked anyone with information to get in touch.
