The office building was rented by a fraud company. What should the property management unit do?

There are two ways. The property management unit loses money and fails to take measures to collect rent and deposit in advance before leasing. If the building is empty, the property management unit can recover the loss through litigation only if the police do not identify it as fraud after calling the police. The police found fraud, and the property management unit waited for the police to solve the case and deal with the results. On the other hand, other natural persons or companies that have business dealings with fraud companies will find property management units, which will cooperate with the police to do a good job in investigation and evidence collection, and hopefully catch fraud gangs.
