Caller left message: "Hi this is officer Jack Marshall from Federal Law Enforcement. We are trying to reach you to notify you that we have received a legal lawsuit complaint on your name and identity.  So give us a call as soon as possible."  No federal agency name, and they would not try to contact you in this way.  They would serve you legal papers.

Caller left similar message as R. Thompson.  Some east Indian sounding guy saying they received a legal affidavit in my name.  I think he said "federal law enforcement" as well but like I said he had a thick east indian accent so all i could understand was "this is Agent....from....Law Enforcement."

got the same message today. Thick asian sounding accent. Pretty sure its a scam.

They all me today. But said they was from the IRS. And when I wouldn't give my name. The  foreign accent man told me to [***] off and hung up on me. Really!!!!

Indian and Pakistani scammer/extortionists.  They often engage in sexually abusive talk when they find their scams aren't working. Simply
ignore and block the calls.
