SEOUL: South Korean prosecutors on Monday sought the arrest of the heir to the Samsung empire over a scandal that has seen the country’s president impeached, in the latest setback for the giant conglomerate. Samsung, the world’s largest smartphone maker, is already reeling from the international debacle over its Galaxy Note 7, which was recalled after some devices caught fire. Prosecutors investigating the corruption scandal said they asked a court to issue an arrest warrant for Lee Jae-Yong, the only son of Samsung group chairman Lee Kun-Hee. The Seoul Central District Court said it would rule on the request on Wednesday. Samsung’s revenue is equivalent to a fifth of South Korea’s GDP and Lee’s arrest could have an “important” impact on the economy, a spokesman for the prosecutors acknowledged. “But we believe that achieving justice is more important,” he said. The scion is vice chairman of Samsung Electronics, the firm’s flagship subsidiary, and the de facto head of the group after his father suffered a heart attack in 2014. If prosecuted and convicted he could face a maximum five years in prison, but leading South Korean businessmen have previously been given suspended terms for such offences — including the elder Lee. The announcement sent the share price of Samsung Electronics — South Korea’s largest listed firm by value — falling 2.14 percent, shaving more than $5 billion off its market capitalisation. Samsung is already trying to repair an image tarnished by the Note 7 recall crisis and faces stiff competition from Apple and smaller Chinese rivals. “This is a big crisis for us,” Yonhap news agency quoted an unnamed senior Samsung executive as saying. “We have to make aggressive investment and merger and acquisition decisions to race ahead of competitors. “But we are afraid that the latest development would cause great delays in our decision-making process.” But Greg Roh, analyst at Seoul-based HMC Investment & Securities, said the firm had a “very well-organised management system” and was not driven by “a certain personality”.
