An employee found lacing a colleague’s lunch with a toxic substance has led German police to investigate whether the deaths of 21 other people at the business were the work of a serial killer.

Global media outlets have reported that authorities in the town of Schloss Holte-Stukenbrock – approximately 134 kilometres south-west of Hanover – were alerted to the astounding situation after an employee noticed something suspicious on his lunch.

An examination of video footage at the business allegedly identified a colleague of the man spreading a powder over the food.


Residue on the sandwich was then sent for testing, which was found to be a poison capable of causing severe organ damage, according to the reports.

The alleged perpetrator’s home was then raided, where substantial quantities of heavy metals are believed to be have been found.


As a result of the disturbing find, police have reportedly launched an investigation into the deaths of 21 other former employees of the company, dating back as far as 2000, all of whom had died from cancer or a heart attack shortly before retiring.

It is feared those 21 other deaths could have actually been the result of heavy metal poisoning.

Media identified the business as ARI Armaturen, a global manufacturer of pressure control valves.

ARI Armaturen has been contacted to confirm whether it is the business in question, and if so, whether it is willing to comment on the situation.



On its website, the business, established in 1950, said it employs over 800 staff globally, and has 20,000 products being sold in more than 50 countries.
