Eleven other women accused Spanish opera singer Palacido Domingo of harassing allegations that the man described yesterday as "full of contradictions".
The accusations, published three months ago by the Associated Press, follow similar allegations published in August by the agency, which are linked to more than 36 singers, dancers, musicians, schools and employees who said they saw or experienced inappropriate behavior from Domingo.
The Los Angeles Opera House, run by Domingo, said in August it would seek outside legal advice to investigate the allegations.
She said she took the accusations "very seriously" but declined to give further details as the investigation continued.
Domingo's agent said the new allegations "are as full of contradictions as the first novel, in many ways, simply untrue."
"Due to the ongoing investigation, we will not go into details," said spokeswoman Nancy Seltzer.
Domingo, 78, is one of the most famous classical singers in the world and has performed in several opera houses around the world.
