Russia's prosecutor-general's office says Moscow prosecutors must reclassify the attack on a well-known Muslim singer and regional culture minister as a hate crime.
The office issued a statement Monday ordering that the charges of "hooliganism" be changed to infliction of serious bodily injuries motivated by ethnic, racial and religious hatred.
It said it cannot understand why authorities ignored the insults the suspects allegedly shouted.
A group of young men beat and seriously injured Zaur Tutov Saturday in Moscow. He is culture minister in the mainly Muslim southern Russian republic of Kabardino-Balkariya and a popular singer.
Tutov was attacked when he went to meet his daughter at a Moscow cultural center. Witnesses say the suspects yelled "Russia is for Russians" during the beating.Some information for this report was provided by AP.
