The case against the Rocky actor, 71, was presented by the Santa Monica Police Department.

In December, the same police force revealed they were investigating a complaint made in November 2017, relating to an alleged incident in the city in the 1990s.

Stallone had previously issued a denial over reports that a 16-year-old fan had accused him of sexually assaulting her in Las Vegas in the previous decade.
