Caller said his name is Alex Watson. (Very heavy Middle Eastern accent)   From Legal Affairs & Investigation. (What dept was never indicated)  About a Criminal Investigation on me. When pressed him about the issue, I was hung up on. When I tried to call back, there was no answer. Not sure what legal dept wouldn't have, at the very least, an answering machine.
After doing a little digging myself, I realized there's about 50 other people that have also received the same kind of calls. Some were even told this guy was from the IRS and wanted money that was owed!  Was thinking of reporting this to local PD, but am looking for advice  (?)
