Criminal case opened after Sarco capsule – which releases nitrogen gas at the touch of a button – used in Merishausen

Police in northern Switzerland say several people have been detained and a criminal case opened in connection with the suspected death of a person in a new “suicide capsule”.

The “Sarco” capsule, which has never been used before, is designed to allow a person inside to push a button that injects nitrogen gas into the sealed chamber. The person is then supposed to fall asleep and die by suffocation in a few minutes.
