An executive from British consumer goods giant Reckitt Benckiser was slapped during an emotional news conference as he apologized over deadly lung injuries linked to the use of humidifier sterilizers marketed by the firm.
Ata Safdar, head of Reckitt Benckiser Korea and Japan, bowed several times in apology before an audience that included victims and their families, among them a 13-year-old boy who now uses an oxygen tank to breathe.
The news conference in a Seoul hotel marked the first public acceptance of responsibility by the firm for its role in a bitter controversy that has raged since 2011.
The government said last year that 92 people were believed to have died from causes related to the humidifier products - not all them marketed by Oxy Reckitt Benckiser, which was the group's South Korean arm at the time.
"Today’s apology, was about acceptance of responsibility for the harm that Oxy HS (humidifier sterilizers) has caused," Safdar said.
"This is the first time we are accepting the fullest responsibility, and we are offering a complete and full apology.
"We were late, five years have passed, we are also apologizing far too late. This is what we are apologizing about."
As he spoke, a man stepped on to the stage, shouting expletives and slapping him on the back of the neck.
"This is heartbreaking," Safdar said as he asked to be allowed to continue. "I apologize again. I would request that I am allowed to finish my statement, please."
Another man who mounted the stage shouted: "It's too late."
Sales of the sterilizers, a liquid added to the water of humidifiers, were suspended by the South Korean government in 2011.
Safdar said some 178 users of its products are among those believed by the South Korean government to have been affected, and he outlined a plan to set up a compensation panel.
South Korea says 530 people had registered claims since 2011 of lung ailments from using humidifier sterilizers marketed by Oxy Reckitt Benckiser, and similar products marketed by other firms.
South Korea is believed to be the only country where the products were sold, according to a government official.
South Korean prosecutors have opened a criminal investigation against makers of the products.
The company changed the name of its local unit to Reckitt Benckiser Korea in 2014.
Reckitt Benckiser's global brands include Dettol antiseptic wash and Durex condoms.
The apology follows a written statement by the local unit of the company for failing to communicate more quickly with victims and their families. Last month, the firm established a 5 billion won ($4.4 million) "humanitarian fund", which was in addition to a 5 billion won fund set up in 2014.
