Former Mungiki leader Maina Njenga was on Monday arraigned after spending five nights in police custody.
He was driven to Makadara law courts under tight security ahead of his arraignment over claims of planning anti-government protests against the high cost of living.
He had been arrested on July 20 by police from lower Matasia in Ngong and taken to an undisclosed location, his lawyer Ndegwa Njiru said.
The lawyers moved to court under habeas corpus and obtained an order requiring police to produce him in court on July 24.
Habeas corpus is a writ issued by a court directing one who holds another in custody to produce the person before the court for a specified purpose.
Njenga is among dozens of leaders detained for days by police over claims of organizing the protests.
The countrywide protests were called to denounce the high cost of living and the new Finance Act 2023.
More protests are planned for this week amid the police crackdown.
Police have been criticized over their brutality which left up to 15 people dead and others wounded.
