My wife received a call from this number, they left a voice message saying " this is from IRS, an arrest warrant has been issued etc." when I called back, they were really rude and started vulgar words in Hindi, I disconnected and they called back a couple of times and I didn't answer anymore. BTW the caller was from India.

I recieved a call from this number and let it go to voicemail. An automated system left a message that "an arrest warrant has been issued for me. It is very important that I call back at 513-449-6782."

They left an arrest vmail from +1 (513) 449-6782.

under arrest?
