A fire swept through a South Korean hospice for elderly, infirm patients early Wednesday, killing 21 people.
Most of the victims died from asphyxiation, rescue officials said, as the fire on the upper floor of the three-storey facility filled the rooms and corridors with toxic clouds of choking smoke.
Another seven people were injured, six of whom were in a critical condition as the result of excessive smoke inhalation.
The fire broke out shortly after midnight at the hospice in Jangseong county about 190 miles (300 kilometres) south of Seoul.
The facility cared for close to 80 chronically ill, often bedridden patients, including stroke victims and advanced Alzheimer´s sufferers.
Local police chief Roh Kyoo-Ho said an 81-year-old male patient with dementia had been taken into custody after CCTV footage showed him entering a storage room where the fire was believed to have started.
“We are focusing on the possibility of arson,” Roh said, while adding that the man, identified only as Kim, had denied any involvement.
“We found a cigarette lighter at the scene and forensic experts are examining it,” he added.
One of three nurses on duty died as she tried to douse the flames with a fire extinguisher.
