Andrew Kreisberg, executive producer of The CW's DC Comics series including The Flash, Supergirl and Arrow, has been suspended by producers Warner Bros. Television Group over allegations of sexual harassment from multiple women.

Warner Bros. Television, the studio behind the Greg Berlanti-produced comic book adaptations, has launched an internal investigation into the claims leveled against Kreisberg.

"We have recently been made aware of allegations of misconduct against Andrew Kreisberg. We have suspended Mr. Kreisberg and are conducting an internal investigation," Warners said late Friday in a statement. "We take all allegations of misconduct extremely seriously, and are committed to creating a safe working environment for our employees and everyone involved in our productions."

All of the younger-skewing network's DC comic book shows are produced by Berlanti Productions and his head of television, Sarah Schechter. Kreisberg served as showrunner on Arrow and The Flash — The CW's two highest-rated originals — as well as Supergirl, Legends of Tomorrow and CW Seed entry Vixen. It's unclear if production on any of The CW's live-action shows will be impacted, as all of them are currently filming.

"We were recently made aware of some deeply troubling allegations regarding one of our showrunners. We have been encouraging and fully cooperating with the investigation into this by Warner Bros.," Berlanti and Schechter said in a joint statement. "There is nothing more important to us than the safety and well-being of our cast, crew, writers, producers and any staff. We do not tolerate harassment and are committed to doing everything we can to make an environment that’s safe to work in and safe to speak up about if it isn't."

Nineteen men and women, all of whom chose to remain anonymous, came forward to Variety, which first reported the allegations, to accuse the showrunner of sexual misconduct, including inappropriate touching, which took place over a period of several years. Many are current or former employees of the shows Kreisberg executive produced. Kreisberg allegedly touched people and kissed women without consent and asked for massages from female staff. None of his accusers reported the alleged behavior to the HR department, though they claim the producer fostered a "toxic" work environment in which women were evaluated "based on their bodies."

Kreisberg has denied the allegations. "I have made comments on women’s appearances and clothes in my capacity as an executive producer, but they were not sexualized," he told Variety.

Berlanti is one of the top showrunners in television, and Kreisberg is his top creative lieutenant, responsible for writing and producing multiple shows on The CW's schedule, which has become increasingly more reliant on the DC Comics fare. Kreisberg, repped by WME, has a long history with Berlanti, with the duo having worked together on ABC's Eli Stone in 2008-2009. Reps for WME did not immediately respond to The Hollywood Reporter's request for comment.

The allegations against Kreisberg and his subsequent suspension come on the heels of FX cutting all ties with Louis C.K. after the comedian-producer confessed that sexual-misconduct allegations raised by five women in a New York Times story were indeed true. C.K. has since lost distribution on his movie I Love You, Daddy, had his second Netflix stand-up special canceled and has been dropped by his agency and longtime publicist, among other fallout.

Netflix, among others, also cut ties with Kevin Spacey following sexual-misconduct allegations. Spacey will be written out of the final season of House of Cards — the drama he stars in and executive produces — should the series return from its hiatus as producers Media Rights Capital determine its future. Additionally, in a groundbreaking move, the actor will be replaced by Christopher Plummer in Ridley Scott's upcoming J. Paul Getty feature film All the Money in the World.
