A Lagos state government judicial panel began hearings on Tuesday, a week after the killing of activists protesting police brutality in Nigeria.
President Muhammadu Buhari tweeted on Sunday that the panel had his "full support", but protesters say his administration has for years ignored their calls for reform.
Demonstrators took part in daily protests across Nigeria for nearly two weeks over widespread claims of kidnapping, harassment and extortion by a police unit known as the Special Anti-Robbery Squad (SARS).
