CHAPEL HILL, N.C. (AP) - Officials with the University of North Carolina at Chapel Hill say they've responded to questions from federal education officials about campus response to sexual assault cases.

The school had until Thursday to file its response to questions from the Office of Civil Rights within the U.S. Department of Education. OCR sent a letter in March, saying it would investigate the school after five women filed a complaint in January about how UNC-CH handles sexual assault cases.

The five women alleged violations of Title IX, education's gender-equity law, in the handling of sexual assault cases. They filed another federal complaint under a law that often deals with the underreporting of on- and off-campus crimes. UNC-CH has denied underreporting crimes.

The OCR has never issued its biggest punishment, withdrawal of federal funding.
