I got investment scammed

I got investment scammed by a group, Gao Jianhong's group. A stock investor, Zhang Hetian, actively added me as a friend and introduced Liu Yixin, the chief analyst of anue fund, and his assistant Lin Shihan. At first, I used a normal account and made some profits, so I downloaded the app 'Fenghui' later when Liu Yixin and Lin Shihan told me to join the private equity program. Then I wire transferred through the manager Zhang. I didn't suspect it was a fraud when I saw the chief analyst of anue fund. The withdrawal was normal at first, but later I had to pay 20% of the tax before I could withdraw the fund. Now I have called the police, and I know I am a fool, but please help me, everyone.
