Actor Thomas Middleditch has been accused of groping multiple women as part of a report on sexual misconduct at a Los Angeles goth nightclub. The "Silicon Valley" star seems to have acknowledged it to at least one accuser.

Middleditch declined to comment on the Los Angeles Times’ investigation, but an alleged victim shared messages from him saying he was “so ashamed [he] made you uncomfortable.”

At the center of the scandal is the Cloak & Dagger club, a defunct Los Angeles establishment known for its secretive, underground ambiance. Lowered inhibitions and acceptance of unusual tastes were part of the club’s appeal, but a bevy of women say the owners didn’t care when behavior crossed the line into sexual harassment or assault.

Middleditch is implicated by Hannah Harding, who was 21 when she said Middleditch approached her on the dance floor to proposition her sexually. He was rejected but continued to approach her, she claims, eventually groping her in front of her friends and operations manager Kate Morgan.

Morgan says she reported it to her bosses, but they refused to kick Middleditch out.

“I felt like they dismissed it,” she said. “I told Adam that he needed to listen, that this was not OK.”

Harding said she saw Middleditch grope another woman after she complained. Morgan’s bosses eventually did get back to her, but it was to tell her she was wrong about what had transpired.

“Adam called me ‘to make sure and get a second opinion on him’ because they didn’t trust my story in the first place. They cared more about famous people at their club than women’s safety,” Harding said.

Middleditch later reached out to Harding on Instagram.

“Hannah I had no idea my actions were that weird for you ... I know you probably want to just put me on blast as a monster,” he wrote. “I don’t expect you to want to be my friend or anything ... I am so ashamed I made you uncomfortable.”

The Clock & Dagger, meanwhile, faced a revolt from female members who say the club’s secrecy rules and tolerance for sexual impropriety by famous individuals created a dangerous environment that victimized numerous patrons.

“[Club co-founder Michael Patterson] said he wanted to have a ‘real cult,’” Morgan said. “We all felt complicit but realized we’d been duped as well.”

Patterson denies making the comment.

“My goal for Cloak & Dagger was to create an atmosphere that would inspire people to be their best and most creative self,” he told the Los Angeles Times.

“Our goal from day one was to create the safest space possible,” co-founder Adam Bravin said.
