Investigators to again summon Samsung heir

South Korean prosecutors investigating the corruption scandal involving impeached President Park Geun-hye said on Sunday that they plan to summon Samsung heir Lee Jae-yong again as they look into bribery allegations between Park and the country's largest business group.

Lee, the billionaire vice chairman of technology giant Samsung Electronics, will be summoned along with two other group officials tomorrow morning, said Lee Kyu-chul, the spokesman of the prosecution team.

Investigators had sought to arrest Lee when they summoned him last month, but a court ruled there wasn't enough evidence to justify Lee's arrest at that point.

Investigators will question Lee over new findings they made in the past few weeks and may consider requesting an arrest warrant for him again, said the prosecution

spokesman.

The investigators also want to question Park in person, but have yet to agree with her office on how and when to do it.

On Friday, prosecutors filed a lawsuit against the presidential Blue House to try to force Park's aides to stop blocking searches of her compound. They tried to enter the Blue House with a court-issued warrant to collect evidence earlier this month, but Park's aides turned them away, citing a law that can block searches of sites containing state secrets.
