Prosecutors on Thursday expanded the criminal charges against Cuba Gooding Jr., accusing him in court papers of having groped a third person, this time an unnamed individual who complained the actor touched “intimate parts” without consent at a Manhattan nightclub last year.

The new charges, unsealed in the afternoon, did not specify where Mr. Gooding touched the person, but court papers said the encounter occurred on the night of Sept. 9, 2018, after 11:15 p.m., at Lavo, an Italian restaurant on 58th Street with a downstairs nightclub. He had previously been charged with grabbing a woman’s breast at a rooftop bar near Times Square in June and pinching the buttocks of a woman who served him at a nightclub in October 2018.

The Manhattan district attorney’s office wants permission from a judge to admit as witnesses a dozen other women with similar complaints about Mr. Gooding starting in 2001, even though he has not been charged in those instances. The women accused Mr. Gooding of acts such as grabbing their rear-ends, biting, licking, and forcibly kissing them without their consent.

At State Supreme Court in Manhattan, an assistant district attorney, Jenna Long, told Judge Curtis Farber that there were several additional witnesses that they planned to submit to the court and were in the process of interviewing.
