It's the first time the head of Samsung Group has been arrested in its almost 80-year history.
Lee Jae-yong's arrest was one of the main focal points during Friday's afternoon's briefing by the independent counsel spokesperson.
"With the arrest warrant issued, the team will be sure to investigate any issues that haven't been adequately covered. And of course we will not only indict Lee but will ensure we are still able to prosecute the case."
Lee will now stay at the detention center in Uiwang, south of Seoul, where he had been held since Thursday night before the ruling.
The conglomerate's decision-making body, the Samsung Future Strategy Office, says it will do its best to prepare for the trial and uncover the truth behind this case.
The Seoul Central District Court had approved the arrest warrant requested by the independent counsel team in the early hours of Friday morning.
This was the team's second request, which it filed on Tuesday.
In filing for the second warrant, the counsel expanded the charges against Lee to include diverting assets overseas and concealing the gains from a criminal act.
That's on top of the original charges of bribery, embezzlement and perjury the team filed against Lee with its first arrest warrant request that was rejected last month.
The court explained its ruling via a text message to reporters, saying (quote) "the rationale for and the necessity of Lee's arrest is acknowledged considering the new charges and additional evidence collected."
The Korean tech giant is accused of giving nearly 38 million dollars to entities controlled by President Park's confidante Choi Soon-sil, in exchange for support of a 2015 merger of two Samsung affiliates, that was deemed critical to finalizing Lee's succession to the top of Samsung Group.
The independent counsel's initial mandate to compete the investigation expires in exactly 11 days, so the team has requested a 30-day extension. It's now awaiting the result but working as fast as it can in the meantime to connect all of the loose threads of the case.
