It's no threat, it's a gambit. He's betting on you being too stupid to know better. There's no way police would warn you; giving you time to: grab a gun, secure hostages, effect a getaway...
If uniform officers were coming for you, you wouldn't be at home conversing on the web, you'd be in a jail cell calling your lawyer.
Caller said something about letter of intent for legal representation. Did not say what it was about. Cannot find a legal firm with this number on the internet. I think it is bogus.
Message similar to the one reported by person before me. They asked for my son. Of course they don't say who they are just wanting to clear up some legal matter before they serve the papers. Of course it's BS.
Caller said his name was Michael Radcliff. When asked what company he was with, he stated that he is a processor in Harris County (which is 713 by the way dumb***). Said that he was about to process paperwork and wanted to give me a chance to avoid appearing in court, Gave me a number to call 716-809-8253. I called the 512 number back and a female answered with "something" financial. When I asked her to repeat she just kept saying "what can I help you with sir"
