Actor Sylvester Stallone is denying a claim he sexually assaulted a woman in California in the 1990s.

According to TMZ, an unidentified woman filed a police report in mid-November alleging the now-71-year-old Rocky star raped her at his Santa Monica office in 1990.

A spokesman for the Santa Monica Police Department confirmed to Reuters that law enforcement was investigating the matter, and would refer its findings to the district attorney.

The 27-year-old accusation would fall well outside the state’s ten-year statute of limitations on rape and sexual assault cases.

“We got a complaint that was made in November of alleged sexual misconduct in the 1990s,” SMPD spokesman Saul Rodriguez said. “We are looking into it and will gather information and whatever we discover will be passed to the district attorney.”

Stallone reportedly admits to spending three days with the woman during a film shoot in Israel in 1987, but claims that he never saw her in 1990, the year the incident is alleged to have taken place.

Stallone’s attorney, Marty Singer, told TMZ Thursday the actor may be planning to take legal action against the accuser for filing a false police report.

“My client categorically disputes the claim,” Singer said in an emailed statement.

In November, the Daily Mail reported that it had obtained a police report filed in Las Vegas in 1986 in which Stallone was accused of pressuring a then-16-year-old girl to engage in a threesome with himself and his bodyguard, Mike De Luca.

A representative for the actor called the allegations a “ridiculous, categorically false story,” and said Stallone had never been contacted by law enforcement over the alleged incident.

Stallone is the latest prominent figure in Hollywood to have been accused of sexual misconduct in recent months, as part of the ongoing scandal first sparked by a now-infamous October New York Times exposé on film producer Harvey Weinstein.
