I have recently discovered a customer who makes deposits of cash almost daily. They are not large amounts. In researching, I have seen many checks written to a large retail store for even amounts. I dug a little deeper and found that he works for the store. It appears that he will write them a check, they cash it, he brings the cash to the bank, the checks are held and ran later. We have spoken with him and he says this is a perk for working for the company.Not sure how that could verified. We are needing advise on what we should actually do at this point. Is a SAR justified? Would we mark the box for (other) under suspicous activity?
