Former Google executive Andy Rubin has been accused of running a sex ring, according to a civil complaint filed by his estranged wife.

The Android co-founder reportedly received a $90 million severance from Google in 2014 in the wake of misconduct allegations against him. He was also accused of telling his wife “you are my property, and I can loan you to other people,” according to a report by the New York Times last year.

Now, newly unsealed court documents from a civil complaint filed by his estranged wife Rie Hirabaru Rubin last October accuse him of having several mistresses, at least one of which was “complicit” with him in “running what appeared to be a sex ring”.

“[She] discovered that Rubin had a secret life with multiple women, not just friendships with ex-girlfriends. Rubin had, in his own words, ‘ownership’ relationships with other women, whereby Rubin would pay for their expenses in exchange for offering them to other men. [He] did so that he could watch them engage in various sexual acts, often involving threesomes. One of these women was complicit with Rubin in running what appeared to be a sex ring”.
