* Bolshoi performers have doubts about police case * Administrators point to wider conspiracy * Uncertainty over motive in acid attack By Maria Tsvetkova and Steve Gutterman MOSCOW, March 11 (Reuters) - The confession of a top dancer to plotting an attack on the artistic director of the Bolshoi Theatre's ballet company may not be the final twist in a scandal that has shocked Russia.

Johannesburg, Mar 7 (EFE).- Don Quixote has exchanged the plains of La Mancha for the South African savannah to right all wrongs, according to custom, although now he is ready to go up against evildoers with an unusual weapon: a ballet with a Cuban accent. The organization responsible for the new version of the "Knight of the Sad Countenance" is South Africa's Mzansi Ballet, which will debut its "Don Quixote" in Johannesburg on Friday.

A leading Bolshoi Theatre dancer admitted in court Thursday that he ordered an assault on the famed Russian ballet troupe’s artistic director but denied ever planning the use of acid to ruin his sight. The Moscow district court ordered leading Bolshoi soloist Pavel Dmitrichenko remanded in custody until at least April 18 while the investigation proceeds. It was later to make similar decisions on the two other suspects arrested in raids on Tuesday -- the suspected perpetrator of the attack and the getaway driver.
