<Anchor> The



police are currently investigating the case of two people who drank bottled water in the office and suddenly fell unconscious.

Police believe that it is highly likely that a 30-year-old who took his own life while working for the same company may have added agricultural pesticides to the bottled water before his death.

Two days ago, at a company in Yangjae-dong, Seoul, two employees suddenly collapsed after drinking water from a bottle of water.



[Witness: It was because I was lying down when I came down.

When a woman goes, a female employee (ambulance) rides, and when a man collapses, a male employee rides in the back with him.]



Unlike a woman in her 30s who was discharged from the hospital, a man in his 40s is still in critical condition.



The day after the incident, Kang Mo, a man in his 30s, an employee of the same company, was found dead at his home after absenteeism.




The National Forensic Research Institute gave the first oral findings that Kang's cause of death appeared to be drug addiction, but as a result of SBS coverage, several toxic substances such as 'sodium azide' and 'methanol' were found in the house where Kang died.



Police believe that it is highly likely that Kang, who died, put 'sodium azide' in the bottle of water.



About two weeks ago, another employee of the company collapsed after drinking soda, and 'sodium azide' was found in this soda, and related search records were also confirmed on the mobile phone of Mr. Kang, who died.



Sodium azide is mainly used as a raw material for agricultural pesticides and herbicides, but it is soluble in water and has no special color.



You can easily buy it on the internet as well.



The police booked the deceased Kang on charges of special injuries to two colleagues.



They do not have the right to prosecute, but they intend to investigate the facts of the case by collecting evidence through a compulsory investigation method.



Police are waiting for the results of analysis of the ingredients of the bottled water that the two collapsed employees drank.
