Martins, who is also the head of the School of American Ballet in New York City, has been suspended from teaching classes until further notice.
"We, together with New York City Ballet, promptly engaged an independent law firm that specializes in such matters to conduct a thorough investigation, despite the anonymous nature of the letter and the lack of specifics," the School of American Ballet said in a statement issued earlier this week. "Thus far, the investigation has not substantiated the allegations in the letter or discovered any reason to be concerned about student safety."
Individuals interviewed anonymously by The New York Times told the outlet that Martins has a reputation for giving preferential treatment to company dancers who engage in sexual relationships with him. The interviewees were two retired NYCB dancers and three former SAB students.
