Appearing haggard and unkempt, Pavel Dmitrichenko was shown in a police video confessing to plotting the attack, in which a masked man threw a jar of sulphuric acid in the face of artistic director Sergei Filin on January 17th.
"I organised this attack, but not to the extent that it happened," he said, apparently meaning he did not intend the attack to go so far.
Two other men who had no known connection to the Bolshoi also confessed in the video released by police.
Russia's Channel One state television reported that Pavel Dmitrichenko's girlfriend, also a Bolshoi dancer, was known to have been at odds with director Sergei Filin over the parts she was being given.
Other media said Dmitrichenko himself had missed out on several top roles at the theatre.
The 29-year-old from from Moscow has danced in the Bolshoi Theatre troupe since 2002 and was to dance in "Sleeping Beauty" this month.
He could now face jail and possibly the end of his dance career.
