The Daily Mail is reporting that actor Sylvester Stallone sexually assaulted a 16-year-old fan when he was filming "Over the Top" in Las Vegas in 1986.

The Daily Mail says it has a police report by a girl who was staying at the Las Vegas Hilton, which is now known as the Westgate, when she met the actor who was playing Stallone's son in the movie. He reportedly introduced her and her cousin to Stallone on July 31, 1986.

A few days later, she saw Stallone, who was 40 at the time, again and asked for an autograph. She also asked for a kiss on the cheek and he responded he would give her one later.

The next day, the girl ran into Stallone's bodyguard and she was given two keys to a room on the 27th floor.

That night she went to the room and met Stallone and his bodyguard, identified as Michael De Luca. She and Stallone began having sex while the bodyguard waited in a bathroom. After a few minutes, stallone allegedly asked the girl if she had ever had sex with two men. De Luca then joined the pair.

The girl told police during an interview that she became very uncomfortable with the situation at that point and that she did not want to have any sexual contact with the bodyguard.

She also said that although there was no actual force, she felt intimidated and that Stallone told her that they would have to beat her head in if she told anyone. However, she ultimately did not want to press charges against the two men. She later signed a no prosecution form and the matter was dropped.

ABC News has received the following statement from Michelle Bega, spokeswoman for Stallone:
