A man suspected to be the rider of the motorcycle carrying the assassin who shot dead Kasipul MP Charles Were on 30 April will be detained for 20 days.

Amos Barasa was arraigned on Thursday at the Jomo Kenyatta International Airport Magistrates' Court, where police sought to detain him for 30 working days.

Their application, however, was declined by Principal Magistrate Irene Gichobi. "Consequently, the said application to detain the respondent (Barasa) at the Parklands Police Station is allowed but for 20 days in the first instance," she said.

She also gave the police permission to access his mobile phone and two SIM cards and directed the matter to be mentioned on 4 June.
