We have no way of anticipating what your probation officer might do. If your probation officer believes the charge, it is possible that he will initiate revocation proceedings; he may also wait to see whether the police authorize a new criminal charge, or may simply choose to let your probation end. Your lawyer is in the best position to assess what your probation officer may do.

Similarly, the question of whether charges are likey to be filed on the 'new' allegation, and what those charges may be, are questions you should pose to your lawyer. The exact charge that might be filed will depend upon the specific allegations being made. Also, you can discuss with your lawyer any facts or evidence that you believe weigh against your being charged.

The allegation, "some girl that claimed I may or may not have raped her", is not a particularly compelling basis for a criminal charge -- if the alleged victim cannot state with reasonable certainty that the sexual assault occurred, in the absence of other corroborating evidence the prosecutor will not be able to prove a case beyond a reasonable doubt. One thing is certain: The officer is hoping that you'll make his life easy by making a self-incriminating statement or by confessing.
