Prosecutors have decided not to file criminal charges in connection with separate sexual abuse allegations against the actors Kevin Spacey, Steven Seagal and Anthony Anderson, the Los Angeles County district attorney’s office said on Tuesday.

Mr. Spacey, the Oscar-winning actor and former “House of Cards” star who has faced numerous allegations of sexual misconduct since last fall, was being investigated in connection with an allegation that he sexually assaulted a man in West Hollywood in 1992, the authorities said. Prosecutors declined to move forward with that case because it fell outside the statute of limitations, according to paperwork filed Friday.

Mr. Spacey is still under scrutiny in connection with an allegation that prosecutors received on Aug. 21, Greg Risling, a spokesman for the district attorney’s office, said in an email. The details of the allegation were unclear.
