I received the same call about IRS issue , and that the Police will come arrest me. I called the local 911 and the local police they said " do not worry it is a scam.
Just got this call 5 minutes ago...But when I started asking questions about the guy calling and his managers contact info and that I will report this..he hang up..Very annoying to get these type of calls..Since I see a lot of messages here, I'm wondering why they haven't caught this guy yet? Anyway, he is still in full operation.
