In a statement on Twitter, the Met confirmed: “We are suspending our relationship with James Levine, pending an investigation, following multiple allegations of sexual misconduct by Mr Levine that took place from the 1960s to the 1980s, including the earlier part of his conducting career at the Met.”
The opera house has come under fire for not acting sooner, having learnt of a police inquiry into a report of sexual abuse in 2016.
The move to suspend Mr Levine came after three men accused the conductor of abusing them as teenagers.
A fourth man came forward with fresh allegations on Monday.
According to the New York Post one of the accusers told police: “I began seeing a 41-year-old man when I was 15, without really understanding I was really ‘seeing’ him. It nearly destroyed my family and almost led me to suicide. I felt alone and afraid. He was trying to seduce me.”
Mr Levine was born in Cincinnati, Ohio, to a musical Jewish family. His maternal grandfather was a chazan, his father a violinist and his mother was an actress.
