New York - Hope Exiner d’Amore said Harvey Weinstein raped her in a hotel room in the 1970s, when he was a young concert promoter in Buffalo.
Cynthia Burr said that during this time, he assaulted her in an encounter that began in an elevator and ended with forced oral sex in a hallway. Ashley Matthau, a dancer with a bit part in one of his movies, said that in 2004, he pushed her down on a bed and masturbated while straddling her. Days later, she said, he paid her to remain silent.
Three weeks after complaints of sexual harassment and misconduct by Mr. Weinstein were first reported in The New York Times, women from different continents, fields and generations have come forward with allegations of rape, sexual assault and groping. New accounts include one previously undisclosed settlement with Mr. Weinstein and expand the time frame of alleged wrongdoing to the 1970s.
Together, the accounts provide a widening tally of alleged abuses, and illustrate the toll on women who say they felt ashamed and isolated as they watched the Hollywood producer walk red carpets, pile up Oscars and showcase his ties to prominent figures.
“This has haunted me my entire life,” said Ms. Exiner d’Amore, now 62, who was in her early 20s at the time of the alleged rape.
She and three other women who spoke to The Times described Mr. Weinstein as inappropriate and unrelenting. Some said that he used the pretext of work to lure them to hotels, that he touched them or forced them into unwanted sexual activity and that he wouldn’t stop when they said no.
Ms. Matthau, the dancer who reached a settlement with Mr. Weinstein, said she was willing to break its confidentiality clause even if it meant that he might pursue legal damages. “I want to do my part to help bring this to light so it doesn’t happen with other people in Hollywood or anywhere else,” she said in an interview.
The allegations add to those previously documented in The Times, The New Yorker and elsewhere.
Last week, the actress Dominique Huett filed a lawsuit claiming that in 2010, Mr. Weinstein forcibly performed oral sex on her. The same day, Mimi Haleyi, a former production assistant of Mr. Weinstein’s, appeared at a news conference in New York accusing him of the same behavior in 2006.
The New York Police Department is conducting a wide-ranging investigation of allegations against Mr. Weinstein. Detectives with expertise in old cases are reviewing complaints that have come through the department’s hotline, according to a law enforcement official who spoke on the condition of anonymity.
In New York, the statute of limitations for prosecuting rape and other sex crimes depends on the force alleged and the charges considered, but it can range from two years to no time restrictions for the most serious offenses.
Ms. Burr, the woman involved in the hallway encounter in the 1970s, said that she contacted the New York police in recent weeks and that they told her the alleged assault had happened too long ago to be prosecuted.
Women have also spoken to law enforcement authorities in London, Los Angeles and elsewhere in the United States. The London police are investigating three sexual assault cases involving Mr. Weinstein, ranging from the 1980s to 2015.
Mr. Weinstein’s spokeswoman, Sallie Hofmeister, said in a statement that “any allegations of nonconsensual sex are unequivocally denied by Mr. Weinstein.”
