After your probation officer learns of your arrest, he or she will most likely present a warrant for your arrest to the judge, who will sign the warrant.  The police will be notified and may arrive at your home in order to arrest you.  Or, if you are stopped by the police for any reason they will immediately transport you to jail because of the existing warrant. You should hire an experienced probation violation attorney before admitting any violations.  Otherwise, you could be admitting to the new crime and helping the prosecutor prove that case.  Our criminal defense attorneys can usually resolve both the violation and new crime with a “package deal.”
