Fraud during volunteer procurement of drones

I read a news story that people were transferring large sums of money for the supposed purchase of drones for the military, but in the end, they received neither the drones nor their money. The organizer of the scheme and another accomplice have already fled abroad, and one suspect has been detained in Kyiv. If I or my acquaintances have also been in a similar situation, does it make sense to file a complaint with the police, and how can we get our money back if the suspects are now abroad?
