Moscow (CNN) -- The Bolshoi Ballet says the allegations swirling around one of its dancers -- that he choreographed an attack to blind the artistic director -- are "absurd." 

Even an alleged confession in the case does nothing to convince the cast and crew that Pavel Dmitrichenko could be behind the attack that severely burned and nearly blinded Sergei Filin, the Bolshoi employees said in an open letter Wednesday. 

"Unfortunately, the history of our country and our society knows many examples" when results were achieved by "illegal methods, and evidence and proof often turned out to be a fiction," the letter said. 

The group called for an independent commission to probe the attack. 

Moscow police struck back, saying its "investigators do their job honestly." 

Ballet 'villain' arrested: Story in 4 Acts 

The plot laid out by authorities pits Dmitrichenko as the central villain, lashing out against Filin -- a man who often cast Dmitrichencko as the villain in productions. 

What neither side disputes: Someone threw sulfuric acid into Filin's face in January as he entered his Moscow apartment. 

Police say Dmitrichenko had two co-conspirators, one of whom threw the acid. 

Local newspapers had quoted ballet members as saying Dmitrichenko was angry because he thought Filin was stifling the career of Anzhelina Vorontsova -- Dmitrichenko's girlfriend. 

"For everyone who knows Pavel Dmitrichenko, even the idea that he could be the mastermind and the customer of the crime committed in such a brutal form, is absurd," the Bolshoi's cast and crew said in their letter. 
Is that ironic in anyway?
