No one on the line. Called the number back and it claims to be FOP of Indiana calling for donations. Very persistent calling several times a day. I have asked them previously to not call any more. Calls border on harassment. When you tell them you can't afford to help they insist on any amount you can do would be a big help. I have registered with do not call list and filed a complaint with them as well. I don't believe it is police related.
