Caller claimed to be IRS special investigation Agent.
It's a scam. The IRS doesn't call to get your lawyers name or number. I called them back and recorded the conversation. I'm gonna call them back and put a scare into them

Have the same message three times, using my name, alarmingly garbled by a non-English speaker, on my voicemail. Strangely, the message is recorded and is apparently robocalled to our number. As with others above, he said he was from the IRS and was vaguely threatening. It was clearly illegitimate, which is why I googled the number.

Continues to call for an Andrea Hunter who does not have my number nor has he / she for at least three years when I received it.  I do not know if this is a scam or a debt collector but I have asked them repeatedly to remove that number as it is no longer associated with her.   Each time they claim they have and I will not be called again only to be called back from the same San Fran bay area number a few days later.

A client of mine was just called from this number and was threatened with a warrant and arrest if he didn't come up with $4,000 by tomorrow.  Luckily, he is already working with the IRS, so I know this is a scam.  I had the client contact his agent and gave him the phone number.

I received a call on 10/23/13 from "Michael Carter" at (415)662-8528. I returned the call today, 10/24/13 and spoke with a heavy AsianMiddle Eastern accented sounding male who rattled off some kind of purported IRS agent number as "Michael Carter" wasn't available, according to the caller. He requested the name and phone number of my lawyer and I said I had no lawyer, and asked what this was about. He stated the fraud unit was processing a warrant for my arrest for $4,129.00 for back taxes and that the Sheriff would be there to arrest me at 11:00 a.m. on 10/25/13 and all matters of bad things would happen to me, including at least 6 months in jail. I asked if we couldn't work this out and he stated yes pay the $4,129.00 or risk jail, sale of my home, and all matters of bad things. I asked how could I pay the money, cash, check. He didn't want it paid through eftps, but for me to get the cash and call him back when I had it, (I had to do this before 4 today) and I was to go to a Vons Market and once there to call him and he would give me instructions on what to do.  I called back, Jennie (heavy Asian/Middle Eastern accent answered and passed me to "Tray Bell" ,IRS # 900128816,and offered $1,000.00 today and the balance tomorrow. I was placed on "hold" for a hot second for him to get the ok.  I go it and asked for the case number of the case filed against me, he said it had been filed in the Northern District Court of California,as this was where their office was located, he gave me case number IJ28528 as my criminal case number. I asked why wasn't the case filed in the Central District he stumbled very badly. THen I told him that I was aware this was a scam and would report him to the IRS and FBI.
