A friend was cheated. The swindler contacted him and said that he could get a bank loan. As a result, he signed some relevant procedures. The swindler took the money but didn't get it.

If your friend is cheated and doesn't know it.

So he's the victim.

You don't need to bear the corresponding legal responsibility, but this debt bank will definitely ask your friend to repay it. At present, you'd better call the police quickly, because that liar has constituted a major fraud. If your friend knowingly goes to the bank to get a loan from him and the information is forged, then he is suspected of defrauding the loan and needs to bear the corresponding legal responsibility, so now it is necessary to find out whether your friend is an insider.
