A victim was defrauded through an online investment project called "YY Platform". The platform claims to be able to obtain high rates of return quickly, attracting many investors. However, after some time, the platform suddenly shut down and disappeared. Working with the parties involved in the platform, I was able to trace their real identities and bank accounts. I provided relevant evidence, submitted an indictment to the court, and successfully froze their assets. Through a series of legal means, I finally succeeded in recovering the victim's defrauded funds and ensuring that the defendant was held criminally responsible. This victim was financially compensated with my help and serves as a warning to other potential victims.
