Samsung’s heir apparent Lee Jae-yong has been placed under arrest in South Korea, accused of bribery and other charges, the BBC reports.
The case is linked to a scandal that led to the impeachment of President Park Geun-hye.
Samsung is accused of giving donations to non-profit foundations operated by Choi Soon-sil, a friend of Ms Park, in exchange for government favours.
Mr Lee and the Samsung Group deny any wrongdoing.
The acting Samsung chief was first questioned by prosecutors in January, but they decided then not to arrest him.
But he was questioned for a second time earlier this week.
On Friday, the court said it “acknowledged that it is necessary to arrest [Lee Jae-Yong] in light of a newly added criminal charge and new evidence.”
