Just two days after Amanda Bynes was arrested for allegedly throwing a bong out of her 36th-floor New York apartment window and smoking pot in the lobby of her building, the troubled actress has taken to Twitter again to deny the charges – and make some accusations of her own against a police officer who arrested her.
“Don’t believe the reports about me being arrested. It’s all lies,” she Tweeted Saturday afternoon.
“I was sexually harassed by one of the cops the night before last which is who then arrested me. He lied and said I threw a bong out the window when I opened the window for fresh air. Hilarious. He slapped my vagina. Sexual harassment. Big deal. I then called the cops on him. He handcuffed me, which I resisted, quite unlike any of the reports stated.”
Bynes extra-long Tweet didn’t stop there. She provided even more detailed allegations about Thursday’s events (which included a psychiatric evaluation) and her eventual court appearance Friday morning, in which she was attired in sweats and a frizzy wig covering her super-short hair.
“Then I was sent to a mental hospital. Offensive. I kept asking for my lawyer but they wouldn’t let me. The cops were creepy. The cop sexually harassed me, they found no pot on me or bong outside my window. That’s why the judge let me go. Don’t believe any reports.”
The New York Police Department is looking into her claim.
“It’s being investigated by the internal affairs bureau,” NYPD spokesman Det. Brian Sessa told PEOPLE.
