Denise Richards' reps were contacted yesterday by New York City detectives, who say they want to speak with her about the events leading up to the wild incident at The Plaza Hotel ... sources connected with the case tell TMZ.
Richards was with Charlie Sheen hours before his hotel liaison with Capri Anderson. She was also across the hall from Charlie's room and went inside after the incident. And, we're told, Richards went inside the room and saw what could be evidence in the investigation.
We're told Richards has given assurance she will "fully cooperate."
Anderson went to the NYPD Monday and filed a criminal complaint against Charlie for assault and battery as well as false imprisonment.
