Just over a month after several One Tree Hill cast and crew members accused the show鈥檚 creator, Mark Schwahn, of sexual harassment, Schwahn has been fired from his current show, The Royals.

鈥淲e have concluded our investigation and Mark will not be returning to The Royals,鈥 Lionsgate TV said in a statement to Variety. 鈥淭he 4th season of the show has already completed production and will air as scheduled on E! in the spring.鈥

Schwahn was suspended in November following allegations of sexual misconduct during his time on One Tree Hill. In an open letter from 18 of the show鈥檚 cast and crew members, including stars Sophia Bush, Hilarie Burton, Bethany Joy Lenz, and Shantel Van Santen, the showrunner was accused of psychological and emotional manipulation, speaking to female employees in 鈥渄eeply upsetting, to traumatizing, to downright illegal鈥 ways, and putting them 鈥渋n situations where [they] felt physically unsafe鈥 while working on the show.

Following the initial allegations from the OTH cast, 25 cast and crew members from聽The Royals also accused Schwahn of 鈥渞epeated unwanted sexual harassment.鈥 In the wake of his firing from that show, Bush and Burton took to Twitter to react to the news.

Bush praised the women who came forward while issuing a warning to other abusers who have not yet been exposed.

鈥43 women came forward,鈥 she wrote, adding a link to the news of her former boss鈥 firing. 鈥淭o the ones who did and to the ones who didn鈥檛 or couldn鈥檛, I hope this news is a salve to your souls. To the other predators out there? I hope this is a lesson that sometimes, even if it takes time, justice is served. You鈥檙e next.鈥

Burton issued a series of tweets stressing the importance of not issuing 鈥渄egrees of harassment鈥 and praising the cast and crews of shows she worked on following OTH. 鈥淚 had no idea how bad OTH really was until I was taken in by the amazing cast and crew of @WhiteCollarUSA,鈥 she wrote. 鈥Thank you to them for showing me how it鈥檚 SUPPOSED to be. Thank you to the directors who called even though I wouldn鈥檛 audition. Thank you to @GreysABC and @ForeverABC. And most recently @LethalWeaponFOX. You have treated me with such respect and kindness. And my ability to speak up now, all these years later, is because I have seen what filmmaking should be. You can be talented AND kind.鈥

She also gave a special shout-out to her OTH sisters. 鈥淵ou women are amazing,鈥 she tweeted. 鈥淲hen I left all those years ago, I could have never anticipated how strong this bond would remain. It鈥檚 a good day, gals. Your art matters. It鈥檚 what got me here. Xoxoxo.鈥

Schwahn has not commented publicly on the allegations.
