The U.S. Probation Office does not have a tip line. However, if you are aware of someone who has committed a crime, please contact your local police department. If you believe the individual may be under Federal supervision you may report adverse conduct by calling (213) 894-3600 between 8:00 AM and 4:30 PM, and ask to speak to the officer of the day. Please note that the U.S. Probation Office will not confirm the status of the individual.
I want to report a possible violation of probation/supervised release. Do you have a tip line?
