Tara Reid has filed a police report after she says she was drugged in an Illinois hotel … and, in it, she says she’s willing to prosecute those allegedly involved.

The actress filed the report Tuesday, the Rosemont Public Safety Department announced in a press release … and it features a lot of the same information Reid relayed to us in the immediate aftermath of the incident, according to Page Six.

As we told you … Reid says she was at a hotel just outside of Chicago late Saturday night when she went down to the bar for a drink … she says it was crowded with YouTubers.

After ordering a glass of wine, Reid says she went to smoke a cigarette with one of the influencers she met in the lobby … and, when she came back, a napkin had been placed over her drink she didn’t put there. TR sipped from it anyway … and, she told us, she next remembers waking up in the hospital.

Worth noting … Reid has a well-documented history of substance abuse issues — but, she insists she only had one drink at the bar.

P6 reports all of this info made its way into the police report … with the added piece that Tara says she’s willing to help prosecutors secure convictions for any individuals allegedly involved in her drugging her.
