The New York Times reports that a two-month long internal investigation into sexual harassment and physical abuse allegations against Peter Martins, New York City Ballet's former ballet master in chief, has found that the accusations could not be corroborated. In December, an anonymous letter sent to NYCB and its affiliated School of American Ballet accused Martins of sexual harassment, although the claims were non-specific. Afterwards, several former dancers and one current company member came forward to the press accusing him of physical assault and verbal abuse. Martins, who directed the company for 35 years and has denied the accusations, retired on New Year's Day after taking a leave of absence. An interim team led by ballet master Jonathan Stafford has been overseeing the company in the meantime.
