This cell phone # is registered to a Michigan law enforcement agency and has been spoofed or placed on a national automated phone dialing system.  The party assigned to this number is not making ANY of these calls.  The calls appear to be "hang-up" type calls and have gone out to people in every state within the U.S. with no speaking or recorded messages attached. The unwanted calls started on Thurs. Dec. 6th and have continued mostly between the hours of 8:00am till 10:00pm.  It is currently being investigated through AT&T and hopefully the source will be identified and the number removed from the computer dialing base in the very near future. I repeat, the calls are not being made by the agency or the party who has been assigned the number.  A call back or voice message will not be accepted due to the volume of calls mistakenly placed by this number.
