The public prosecutor Frankfurt am Main investigates two police officers on suspicion of bodily harm resulting in death in office. Four days after the two officials had used a so-called Taser against a 49-year-old, the man had died, the agency said.

According to prosecutors, the man was diabetic. He was severely overweight and had suffered from a mental illness. The police had been called on 30 April by an ambulance in the apartment of the man in Frankfurt am Main.

The 49-year-old had fought aggressively against taking urgently needed drugs. That's why the officers wanted to keep him quiet with the Taser. After the electric shock, the man had collapsed, vomited and was taken to the university hospital. There he died according to prosecutors a few days later from pneumonia and blood poisoning.

Frankfurt and Offenbach have been tested since 2017 as Taser's known distance electric impulse device. Now they are being introduced nationwide to the Hessian police.
