Four more women have come forward and accused Robert Knepper of sexual misconduct a month after veteran costume designer Susan Bertram claimed that the “iZombie” actor sexually assaulted her on the set of Allison Anders’ 1992 film “Gas Food Lodging.”

The new accusations against Knepper was published by The Hollywood Reporter on Tuesday. And according to the news outlet, the incidents span decades and are alleged to have happened in both the United States and Canada.

Robin Saex Garbose said that Knepper sexually assaulted her in October 1983 at New York’s Manhattan Punch Line where he was helping to cast a theater production of “June Moon.” Garbose claimed that Knepper — who was auditioning at that time — came into her office, pushed her up against the wall, and started kissing her. “It was physical,” said Garbose, who was 23 at the time.

A woman, who wished to keep her identity anonymous, claimed that Knepper sexually assaulted her in 1989. She was working as assistant company manager for San Diego’s La Jolla Playhouse at the time, while Knepper was a visiting actor for the theatre company’s production of “Nebraska.” The woman, who is now married to a prominent TV actor, claimed Knepper “pinned" her up against the wall before forcefully kissing and groping her.

Meanwhile, stylist Emma Julia Jacobs claimed that Knepper attacked her after she rebuffed his advances in the summer of 2010 during the production of “Planet of the Apes.” The “Prison Break” alum allegedly ripped her pants open before forcing her to perform oral sex.

Lastly, filmmaker Christy Oldham accused Knepper of placing her hand on his crotch during a meal at Miceli’s restautant in Los Angeles in 2013. When they went outside, Oldham said Knepper pushed her up against a brick wall.

According to The Hollywood Reporter, the four women contacted the magazine individually, and that reading about Bertram’s experience encouraged them to come forward.

A day after Bertram’s allegations against Knepper were made public, the actor took to Instagram to deny her claims. “Over the past few weeks, my wife and I have discussed the pain women have experienced and the bravery they have shown in coming forward,” he said. “I am shocked and devastated to be falsely accused of violence against a woman. That’s just not who I am. To those who have reached out today with words of support and encouragement, I thank you from the bottom of my heart.”

After the new accusations against him surfaced, Knepper issued a new statement, insisting that those claims are not true. “We have come to a time where hard-earned careers are being lost on the basis of accusations. I need to reiterate that these accusations against me are false,” he said. “We have lost the presumption of innocence; we have lost ‘due process’; and we have lost the ability to review evidence — allowing the media to become both ‘judge and jury.’ Until I can sit down and have a dialogue with my accusers, managed not by the press but by an impartial mediator, I have nothing further to say on this matter. My wife, family and close friends, know me and my true nature and I am grateful for their love and support.”

Knepper, who is best known for his role as Theodore “T-Bag” Bagwell on the Fox hit series “Prison Break,” was promoted to series regular for the upcoming Season 4 of CW’s “iZombie.” The CW has yet to comment on the claims being made against Knepper. Nonetheless, those allegations could cause potential problems for network and for the show’s fourth season, which is set to air in the early part of 2018.
