Automated message that looped for three minutes, saying that the message's recorder was named James Casten and something I couldn't make out about a magistrate and federal crime, and advising me to cooperate. It sounded like a scam because something that important would have a real person calling and details, like my name, or come from local, not all the way from New York. I called back anyway and nobody ever responded, nor was there a voicemail set up to tell them not to call again.
Left a threaten message , something about being a federal offence etc. I returned the call for fun and somebody answered and didn't say anything then hung up.
As a retired Federal Law Enforcement Agent, this is a scam number. especially if this is to a cell number. when you call back, is the potential to down-load malware to your phone at the other end.
(631) 417-4561 is not legitimate
You may report this number to the State of New York as well as the Federal Trade/Communication Commission and the United States Attorney General's Office since this call is crossing state lines, and this individual is representing themselves as a Federal Prosecutor.
If the Federal Government wishes to contact you, they will do it in person, or by certified letter with the local office address on it, not a voicemail/recorded message.
