Sylvester Stallone responded Thursday to sexual assault allegations leveled against him from an incident in 1986. An unidentified 16-year-old girl said Stallone, who was 40 at the time, “intimidated” her into having a threesome, according to a police report first obtained by the Daily Mail.

"This is a ridiculous, categorically false story,” Stallone’s spokeswoman, Michelle Bega, told TMZ. “No one was ever aware of this story until it was published today, including Mr. Stallone. At no time was Mr. Stallone ever contacted by authorities or anyone else regarding this matter."

The girl claimed Stallone and his bodyguard, Michael De Luca, intimidated her into having sex with them at a Las Vegas hotel, according to a report filed with the Las Vegas Police Department. Retired Las Vegas Metro Police Department detective sergeant John Samolovitch confirmed to the Daily Mail that the police report was a true copy of the original.

The teenager, according to the report, said she was “very uncomfortable” but felt like she had “no choice” but to engage. Stallone allegedly threatened her, claiming that they would “have to beat her head in” if she told anyone because they were both married. De Luca, the bodyguard in question, was killed in 2013 after he was shot during a traffic stop in California, according to the Observer.

The girl reportedly decided not to pursue charges because she was “humiliated,” “ashamed” and “scared.”

The allegations against Stallone surfaced hours after Minnesota Sen. Al Franken was accused of sexual assault by a radio anchor. Leeann Tweeden said the former "Saturday Night Live" actor groped her and forcibly kissed her in 2006. Franken subsequently apologized and called for an ethics investigation into the situation.
