Same just happened to my elderly mother! Which totally freaked her out. Caller said he was "David Frank" calling from US Department of Treasury, Legal Affairs, He wanted her to pay $6,000+ from 2010 taxes she never owed. Mr. Frank stated that a federal arrest warrant has been issued and she would be arrested and go to jail for 30 days. Thank goodness I am an attorney. My mother immediately contacted me and the individual refused to speak to me. I requested to speak with the gentleman's supervisor and he hung up.
I just received the same phone call. I know it's a scam but a lot of elderly people don't know that and that's who will call them back. Then they'll bleed them dry. Thank goodness your mother had presence of mind to call you.

Do consider getting a call blocking device or phone.. You can google them and many are around $40.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.
