I received the same message, the first time I tried to call it said the Verizon subscriber was unavailable, tried again, and "Officer Mark Robinson" answered the phone, but he hung up right away. Unnerving to say the least even though I am fairly certain I have no issues with IRS.
IRS has absolutely no authority over local police. Local police and law enforcement are NEVER involved in tax disputes. IRS does not arrest anyone. It has no law enforcement capabilities. If law enforcement is needed US Marshals are called upon. But this is very rare.
Received the exact same call ....some complete looser with strong Indian accent pretnending to be some other looser called Steven Bentsen (IRS officer).
Good luck next time you sad sad moron. I hope your life will get better one day and you don't have to waste your time making such ridiculous attempts at scamming people.
