I have a friend thats former employer keeps contacting me in order to get a hold of them to arange a meeting or conversation. My friend no longer wishes to speek with this person so i relayed the message. The former employer has now thretened to contact my place of buissness and slander my name in hopes that this will change my participasion in the matter. The former employer is crazy and i know that he takes medication for the symptums. What legally can i do to make the phone calls and threts stop.
