Nothing illegal going on here except possibly the stalking. If the stalking really bothers you, then keep records of any future stalking activity and then speak to the police about it.
(Also, just curious, what do you mean by "he's in deep with this old man" and now the old man wants to get you involved? Really, this could mean practically anything, from him being in debt to an old man and now the old man wants you to pay the debt, to him being in love with the old man and now your boss wants you to love him too...what?)
