Investigators say the letter demands that the person it's addressed to deposit Bitcoin in exchange for their family's well being.
They're cautioning the public to be vigilant when opening mail and advising anyone who receives one of these suspicious packages to handle it as little as possible.
Police say such items should be placed outside and then covered with an upside down garbage can or something similar to protect it.
Police should then be called immediately so officers can come get the package.
