Seoul, May 28 (IANS): The wife of Korean Air's chairman was questioned by police on Monday over multiple assault and abuse allegations.

Lee Myung-hee arrived at the Seoul Metropolitan Police Agency at around 10 a.m. The police had summoned her last week, reports Yonhap News Agency.

Lee and her two daughters, including Cho Hyun-ah famous for the "nut rage" case, were being probed over mounting allegations of abuse of power, assaults, tax evasion and smuggling of luxury goods.

Lee, 69, is accused of shoving and cursing at construction workers hired for the expansion of a hotel owned by Hanjin Group, which includes Korean Air, in 2014.

She may face a charge of aggravated assault as a witness testified she had hurled scissors at them.

She is also suspected of physically and verbally assaulting workers at her Seoul mansion when it was being remodeleld, as well as habitually abusing company employees, private chauffeurs, security guards and housekeepers.

The police have secured statements from more than 10 witnesses who said they want Lee to be held accountable. By law, assault charges cannot be pressed against a suspect unless victims seek punishment.

But authorities are considering charging Lee with aggravated assaults, in which case, victims' formal complaints will not be required.
