Tara Reid is heartbroken after police closed their investigation into whether or not she was drugged at a hotel bar.

The 50-year-old star - who had alleged she was drugged by a stranger after having just one drink at a hotel in Rosemont, near Chicago, on November 23, before being taken out on a stretcher and brought to hospital - has responded after police closed the case due to a lack of evidence.

In response, she told the Daily Mail newspaper: "All of the bullying I have been subjected to since and everyone twisting reality without the facts they weren't even there to witness is truly affecting my mental health and I need it to stop."

She added: "I am making this statement to help people see the truth of what actually happened so they can understand the facts and how truly heartbreaking this is,"

The American Pie star also alleged that there is 33 minutes of surveillance footage unaccounted for.

She continued: "I am off camera many times and outside where there is no footage. The camera also skips five seconds, to 30 seconds or more many times and are missing key information of events."

She claimed that after seeing the footage, she had only "consumed two glasses of wine the entire time", but came back inside the bar "in a completely different state of mind".

She added: "They are making it seem like I chugged all this wine at once and ended up on a stretcher but after reviewing the footage that is not what happened at all."

A spokesperson for the Rosemont Police has confirmed the case was closed on December 11 as "no other evidence" had come to light after authorities previously said they found no evidence of Reid being drugged.

They added that officers had "spoken to everyone involved" with "nothing outstanding", leading to the decision to shut down the investigation.

The spokesperson added that police "don't want to say what she's claiming is false", acknowledging that there are periods of time "not seen" in the footage.

However, they noted they could only take in the evidence they had, which didn't show proof of the alleged drugging.

They said: "That's all we can do."
