Businessman Philip Nahashon Aroko, linked to the brutal murder of Kasipul MP Charles Were, will remain in custody pending investigations after the High Court allowed the withdrawal of his petition challenging the legality of his detention.

Justice Alexander Muteti ordered detectives from the Directorate of Criminal Investigations (DCI) to continue holding Aroko in police custody.

This came after Aroko, through his lawyers Danstan Omari and Sam Nyaberi, withdrew a petition in which he had accused the police of violating his constitutional rights by detaining him unlawfully.

In the initial application, Aroko had sought to be produced in court "alive or dead," alleging that the police had held him beyond the 24-hour constitutional limit without presenting him before a magistrate.
