I got a  call from this number, I did not answer. He left a message claiming to be, I believe he said Justin William (Indian accent/ very hard to understand). All I could grasp was "if I or my attorneys do not return this call, then he wishes me good luck for the way this situation will unfold for me." He was trying very hard to cover his Indian accent and at the same time trying to threaten me. I don't have a clue as to what department or company he was calling from.

I also got a call from this number, I didn't answer and they left a message basically identical to what Amar described in his post. Pretty obviously a scam.

Got a call just now from this number, with the same message previously described. Definitely scammy. Avoid, avoid, avoid.

I actually called this number back.  He claims to be CRA.  Very much a scam!

justin williams called saying he was from cra and that he had an aphadivid(spelling lol) for my arrest for tax fraud, threatened my job etc he said police were being notified to arrest me within 2 hours....I called the local police and they have had several calls regarding this number and advised me it is definately a scam
