Received a voicemai from this number with caller claiming to be 'law enforcement' stating that I am under 'investigation' and asking for call back otherwise face 'legal action'.  He gave his name as Scott Anderson.  Threatening tone.  

I wish their phone service provider would identify these crooks and publish their names and locations.

I got a call from this number from officer Rodney (Foreign Accent -might be Chinese/Indian/Bangladeshi) , Federal Crime Investigation Bureau, telling me that I owe money to the IRS and I will be arrested in 45 minutes by the local police.  He asked me if I am scared and I said NO and hung up.

I get call like this from different numbers at different days.  How to STOP these?

Same here. A threatening call from "Scott Anderson" with a very strange accent but what sounded to my ear like a South Asian one saying there is a legal case as well and an investigation happening if they don't hear back from me immediately. Thank you for providing the resources of this site where you can find out about these scam mongers.

Got a call from Robin from 202-239-6352 number pretending to be federal crime investigation officer. We called back and asked him for his office location. and also said that we will file a complaint against this number. Then the guy used MF word and hang up. Be aware!! Don't give any private info.
