Samsung heir Jay Lee was arrested in Seoul on Friday morning for bribery, embezzlement, and perjury related to his alleged role in a corruption scandal that led to the impeachment of President Park Geun-hye.
He is now in a 6.56 square meter (71 square foot) detention cell with a toilet in the corner behind a partition, according to Reuters.
Lee has denied any wrongdoing.
The tech mogul is divorced with two children, has a net worth of $US6.2 billion (£5 billion), and ordinarily lives in a $US4 million (£3.2 million) mansion in Seoul, South Korea.
The $US297 billion (£237 billion) Samsung Group that Lee heads is the world’s biggest manufacturer of smartphones, flat-screen televisions, and memory chips, and Lee is accustomed to rubbing elbows with Silicon Valley titans such as Facebook’s Mark Zuckerberg and Apple’s Tim Cook.
