State prosecutors launched a full-fledged investigation into the group last year, with members of the Shin family that runs the conglomerate being implicated in wrongdoing.

The court ordered Shin, 74, to forfeit 1.44 billion won ($1.22 million) she illegally pocketed.

"The defendant, as an executive of a conglomerate, failed to fulfill the basic social responsibility and role of running a company transparently and reasonably," the court said. "She should be held responsible and made to recover damages done to Lotte Group."

Other members of her family, including her father and group founder Shin Kyuk-ho and the group chairman Dong-bin, are currently standing trial without detention over a string of corruption charges. (Yonhap)
