The man who killed 21 work colleagues by sprinkling poison on their lunches

A suspected killer simply known as Klaus O, has been seized by police after footage showed him opening the victim’s lunchbox and placing a suspicious powder inside. The man was detained in Bielefeld, west Germany.




Cops in Bielefeld are now also probing the untimely deaths of 21 of his colleagues. The said colleagues died before they reached retirement age from a “remarkably high number of heart attacks and cancers”.

Three other fellow engineering workers at the factory of ARI Armaturen, the valve manufacturer in Schloss Holte-Stukenbrock, a town nine miles south of Bielefeld, are off sick with mystery illnesses. One employee has been in a coma for two years.

Investigators added that the amount of lead acetate found in the sandwich of a 26-year-old victim was enough “to cause serious organ damage”.

The suspect, 56, has been working at the firm for 38 years.
