Actress Afton Williamson announced on Sunday she is not returning to The Rookie next season, saying she was sexually harassed, assaulted, and bullied on the set.

Williamson played LAPD officer Talia Bishop opposite star and executive producer Nathan Fillion. In an Instagram post, Williamson said the incidents took place while shooting episodes throughout the show's first season. Williamson alleged she was bullied by the executive producers and experienced "racial discrimination/racially charged inappropriate comments from the hair department." She also accused a "recurring guest star" of sexually harassing her and said the "racist commentary and bullying from the hair department head escalated into sexual assault at our wrap party."

Williamson said she told showrunner Alexi Hawley about the sexual harassment, but "it remained undocumented and was not reported to HR as promised." She decided to leave the show for good after learning that a promised investigation had never been launched, she said, adding, "Now is the best time in the world to be a woman and I have a platform, so it's time to use my voice." Representatives for Fillion and ABC did not respond to USA Today's request for comment.
