If it is child sexual abuse, yes.
If it is an adult, no.
However, you have the option of being examined at a hospital with a SANE program where you will be examined (at no cost to you) for any injury and given treatment and information re: STDs (sexually transmitted diseases) and/or pregnancy. Evidence is collected and is held for up to two years. If you chose to report at any time during this 2-year period the evidence will be handed over to the law enforcement agency where the crime occurred per your instructions.
