Monday will be the seventh anniversary of the death of Olaseni Lewis. Now Channel 4 News can reveal that six police officers will face gross misconduct charges, but the hearings will be held in private, although the ruling will be public.
Olaseni had admitted himself to hospital suffering from mental health problems, and was restrained after becoming agitated. Four days later he died.
Tonight his parents tell Channel 4 News of their seven-year struggle since his death.
