from www.tmz.com - Law enforcement sources tell TMZ Charlie Sheen will not be prosecuted over The Plaza Hotel incident back in October.

Capri Anderson -- the porn star who entertained Charlie that night -- filed a police report with the NYPD, accusing Sheen of assault and battery as well as false imprisonment.

Our sources say authorities do not believe Sheen engaged in any criminal conduct -- therefore the case against him will be closed.

We're told an official announcement could come this week.
