Yesterday afternoon in front of a building in Yangjae-dong, Seoul.
An ambulance arrives and after a while picks up the patient in the building.
About an hour later, an ambulance arrives again and picks up another patient in the building.
The patients were all employees of a company located on the 4th floor of this building, and each showed abnormal symptoms after drinking bottled water on the desk and saying "the water tastes strange."
A female employee in his 30s collapsed with convulsions, then regained consciousness and then convulsed once more.
[Witness: It was because I was lying down when I came down.
When a woman goes, a female employee rides (ambulance), and when a man collapses, a male employee rides in the back with him.]
Mr. A was discharged this morning, and Mr. B is still receiving treatment in the hospital.
The police send the bottle of water they drank to the National Forensic Service to request drug evaluation, while investigating the exact circumstances of the incident against colleagues and others.
