For the second time in a matter of weeks, South Korean prosecutors on Tuesday applied for an arrest warrant for the vice chairman of electronics giant Samsung, Lee Jae Yong.
Lee had been questioned on Monday for the second time in just over a month over bribery allegations linked to the corruption scandal that has engulfed President Park Geun Hye, according to local media reports.
Prosecutors have now levelled further accusations besides corruption at Lee, news agency Yonhap reported on Tuesday.
Yonhap also reported that prosectors were seeking an arrest warrant for Samsung president Park Sang Jin, who is likewise accused of being caught up in the scandal.
In January, a court rejected a request to arrest Lee, saying it did not see the necessity.
Although Lee's father, Lee Kung Hee, is officially chairman of Samsung, ill health has seen the younger Lee assume the role of de facto boss in recent years.
Samsung is accused of making donations totalling 43 billion won (36.3 million dollars) to several non-profit foundations operated by Choi Soon Sil, a confidante of Park's, in exchange for Park's support for a controversial merger.
Choi has been charged with using her ties to Park to pressure companies like Samsung to donate money to foundations she operates.
