Russia opened a criminal case against the members of the American rock group Bloodhound Gang on September 9.
Russian Investigative Committee spokesman Vladimir Markin said a case against the members of the band was opened "on counts of inciting enmity and humiliating human dignity."
In August, Russian immigration officials banned the group's five members from entering the country for the next five years.
On July 31, bass player Jared Hasselhoff stuffed a Russian flag down his pants during a concert in the Ukrainian city of Odesa.
The performance was recorded by concertgoers and got widespread attention on the Internet.
Hasselhoff was banned from entering Ukraine for five years on August 6 because he urinated on a Ukrainian flag during a July 30 concert in Kyiv.
