> Yesterday someone tried to deposit money in my account

You opened your post with what is almost certainly the reason for this, especially if this is a frequent occurrence.

Banks are increasingly wary of people other than the account holder depositing into KYC accounts. You probably aren't laundering money, and the bank's compliance department probably doesn't think you are either, but they're still not going to risk having to explain your activity at a KYC audit.

Is it right? No. But this is almost certainly the reason. Chase is one of the more trigger-happy banks at this, but they all do it. If you need to be mad at someone, be mad at the government, not the banks that are required to comply with anti-privacy and anti-freedom regulations.
