According to relevant laws and regulations, in many places, the public security departments of fraud crimes need to lose more than 5,000 yuan, and online fraud costs more than 3,000 yuan. If the loss of the party concerned is below the specified amount, it shall be handled as a general fraud case and the corresponding report record shall be made. A criminal case can be established if the amount exceeds this amount. If the public security organ files a case at the first time and takes action to arrest and detain relevant property before the transfer of criminal proceeds, there will be more opportunities to help victims recover the cheated money. Many people can't file a case because of evidence problems, so it is very important to keep it in time and submit evidence in an all-round way to recover losses.
