About 300 people marched through the Kenyan capital on Monday to protest over what they said was the extrajudicial killing by police of human rights lawyer Willie Kimani, his client and their driver.
Demonstrators carried a mock coffin emblazoned with the words “Stop extrajudicial killings.” Others wore T-shirts with the slogan “Stop police executions.” Some carried placards demanding Interior Minister Joseph Nkaissery resign.
Police officials say they investigate and prosecute any officers suspected of breaking the law.
After lodging a complaint alleging he had been shot and injured by police, Mwendwa was charged with a range of offences, including possessing drugs and resisting arrest, activists said.
The authorities said on Saturday that three police officers had been arrested in connection with the deaths of the three men, who disappeared after a court hearing on June 23
