[US] NYPD transfer me to Shanghai Police for money laundering scam

I am a U.S. permanent resident from mainland China. Today I received a call from NYPD about a violation regarding fraudulent investment messaging on stocks and crypto. The « officer » then claim that the person using my stolen identity to reside in Shanghai. He claim that I need to file a police report within 3 hours or my case will sent to ‘higher authority’. Being scared, I quickly got them to transfer my call to the Shanghai authority. Once connected, the police told me to download Signal messaging app. They were in what looks like a real police station. The PO looks legit as he was wearing a uniform and showed me his badge. Since my mandarin is not as fluent I asked for a translator. This is where I stupidly provide with more information than I should (thankfully nothing major like Chinese ID, SSN, credit card number, etc). They ask me questions like what I was doing on X day and where I was.

It got to the point where they just lecture me about securing my private info and not using public wi-fi. I was kept in the video call for over 3 hours and can’t leave my seat as they think I was being suspicious. As I thought they were finish by filing the police report, they suddenly got some background info about me having a bank account in China.That bank account is associated with notorious money laundering criminals who fled China to come to LA. They were scoffing about how it’s a coincidence that I also happen to be in LA. They began to accuse me of being an accomplice of scamming people and that one of my credit card was found in a safe box in the criminal’s office.

It wasn’t until their « superior » convince them that I have a clean background that they drop their suspicion and lecture me about how dangerous these criminals are. They made me sign some documents about helping them in the investigation and report back every 4 hours to make sure I’m okay and not doing any suspicious activities. They also said to not tell anyone as this is a « secret investigation ». After a few minutes I just couldn’t take it anymore and told my family in which they told me it’s all a scam. At first didn’t believe them but I search on reddit and came across numerous cases similar to mine. That is when I realize I’m not alone. Has anyone experience this before? Sorry for the long rant.
