Roughly four months after JD.com’s billionaire CEO Richard Liu was arrested and later released by Minneapolis police on suspicion of alleged sexual misconduct, local authorities say they will not be charging him in a sexual-misconduct case. In a statement, Hennepin County Attorney Mike Freeman said it was not possible to prove the charges brought against Liu beyond a reasonable doubt. “As is the case in many sexual assault incidents, it was a complicated situation,” said Freeman in the release.
