South Korean prosecutors requested a 12-year prison term for Samsung Group heir Lee Jae-yong over bribery charges at the final hearing in his corruption trial, The Korea Herald reported.

Seoul Central District Court will give its ruling Aug. 25. The Samsung executive, who is alleged of bribing ex-President Park Geun-hye, has been in detention since February. The detention was scheduled to end Aug. 27.

"Samsung Group voluntarily offered funds rather than gave in to former President Park's threats, expecting to get help in the firm's leadership transfer, after it received a request from Park," Special Counsel Park Youg-soo said during the hearing, calling it "a typical case of crony capitalism."

Lee denied all wrongdoing when he took the stand in the trial.
