Synopsis:
In March 2020, police arrested Shizuo Aishima and two executives at Ohkawara Kakohki, a Yokohama-based maker of spray dryers, on suspicion of exporting equipment that could be used to fabricate biological weapons. Despite receiving treatment for cancer at the time, Aishima, who was an engineer, was denied bail and died in custody. Subsequent revelations that police had altered testimony and mishandled the investigation led to the dropping of charges against the company and its employees.
