Legal analysis: China has severely cracked down on online fraud, and the crime standard of online fraud has also improved. According to the relevant provisions of China's laws, if the online fraud exceeds 3,000 yuan, the public security organ shall file a case for investigation after reporting the case. After the investigation is completed, the criminal suspect can be recovered. Therefore, after being defrauded by online fraud, it is usually necessary to call the police, hand over the case to the police, and actively compensate, so as to get the defrauded debt after solving the case. In other words, if the amount of online fraud is more than 3,000 yuan, you can file a case. According to the law, if the amount of fraud is more than 3,000 yuan, the public security organ shall file a case for investigation and investigate the legal responsibility of the perpetrator. If the amount of fraud is small, it has not yet reached the filing standard. You can sue in court and ask the other party to return your funds.

Legal basis: Article 266 of the Criminal Law defrauds public or private property, and if the amount is relatively large, he shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance, and shall also or only be fined; If the amount is huge or there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years and shall also be fined; If the amount is especially huge or there are other especially serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than 10 years or life imprisonment, and shall also be fined or confiscated.
