my grandsons girlfriend is pregnant, and the landlord they just rented from, has been coming on to her and the other female tennant, by suggestive innuindos. Asking her out for coffee and coming up to her work, stopping by their apartment for no reason. My grandson is in jail and can't do anything about it, he is my landlord and I know he does this to all females he thinks are attractive. She is afraid to even answer the door afraid it is him, at night. She is afraid if she complains he will make her move, is there anything she can do about it.? thank you.
