Problem over the scam

Hello everybody.

I have been contacted by West Union Group
I fell into the scam, sadly
I gave them all my informations ( address / name / phone number / bank account )

They sent me 1800€ on my account and I'm supposed to send 1650€ via Western Union to a guy from Ukraine.
Before sending me the money, they didn't tell me what would happen, so I didn't really noticed ( I'm a retard, I know ) what was happenning.

Anyway, how to make me safe from the law of from them ?
I still have their money on my bank account, how to avoid problems at max ?

Thx for your answer.

Call your bank as soon as possible. You want to talk to their fraud department, and be prepared to show them the emails. Let them know that you have now discovered that the transfer was most likely fraudulent--the bank should be able to investigate and reverse the transfer. In the meantime, just don't take out any of the money that was put in your account.

Those persons are gangsters if I well understood. Well, let's suppose I don't want to give their money back.
What will happen ? I'm from France, will they come here ? What are they really able to do ?
Anyway, I can't do anything before this weekend, so I have time to think about it.

The money doesn't really belong to the criminals, it is more likely to be transferred by another victim or deposited in the form of a fake cheque.

You don't really have much choice about giving the money back. Eventually the banks will discover that the transfer was fraudulent and will take the money back from you. Additionally, you may be facing investigation/charges by the police as you will be deemed to have acted criminally.

At the moment you're a victim, but what your considering makes you a criminal. The only difference between you and the original criminals is that you are a lot easier to find and charge than them!!
