Prosecutors said on Thursday that a new charge had been filed against Cuba Gooding Jr., delaying his trial over accusations that he groped a woman’s breast in a Manhattan bar in June.

The Manhattan district attorney’s office said the actor had been indicted in connection with a second incident, but the office did not elaborate on what Mr. Gooding is accused of. A spokesman said the indictment would be unsealed next week.

Mr. Gooding appeared in Manhattan Criminal Court on Thursday for what was supposed to be the beginning of the trial over the initial charges. Wearing a black suit with a white pocket square, he sat in the courtroom for several minutes before prosecutors asked Judge Marisol Martinez Alonso to delay the jury selection because of the new charges.

Mr. Gooding, 51, was to stand trial over an encounter on the night of June 9 at Magic Hour Rooftop Bar, a pricey lounge at the Moxy NYC Times Square hotel in Manhattan. According to the criminal complaint, the accuser said that Mr. Gooding placed his hand on her breast without her consent and squeezed.
