Received call asking for an old friend.  When told I didn't have contact with them they stated that it was related to a legal matter and that I was implicated.  I asked what involvement I would have and they said they had to talk to my friend first before they could say anything to me.  At this point I started asking what organization he worked for and in what department and he told me "IAM" and "Pre-Legal" and then quickly got off the phone before I could ask anymore questions.  Very suspicious call.
