Andrew Kreisberg, who served as executive producer of four different superhero dramas for Warner Bros., has been fired due to sexual harassment claims following an investigation by the company.

A few weeks ago Warner Bros. suspended Kreisberg due to the allegations coming from 19 men and women who claimed to have experienced or witnessed sexual harassment. After conducting an extensive investigation into the claims, the company has now decided to fire the executive producer, Page Six reports.

“After a thorough investigation, Warner Bros. Television Group has terminated Andrew Kreisberg’s employment, effective immediately,” the studio said in a statement.

Greg Berlanti of Berlanti Productions, which produces the shows for the studio, also issued a statement regarding Kreisber’s departure and voicing his support for his alleged victims.

“Warner Bros. Television Group recently concluded its investigation into the allegations against Andrew Kreisberg,” Berlanti said. “We encouraged and supported this investigation, we believe and support the individuals who came forward, and we agree with the studio’s decision. Nothing is more important to us than the safety and well-being of all our colleagues — coworkers, crew and staff alike.”

Kreisberg served as executive producer for the popular “Supergirl,” “The Flash,” “Arrow,” and the “Legends of Tomorrow.” Along with the announcement of his firing, Warner Bros. announced some producer changes that will occur due to his departure.

“Greg Berlanti will assume additional responsibilities on both ‘The Flash,’ where he will work closely with executive producer/co-showrunner Todd Helbing, and ‘Supergirl,’ where he will work closely with executive producers/co-showrunners Robert Royner and Jessica Queller. We remain committed to providing a safe working environment for our employees and everyone involved in our productions.”
