A woman was arrested early Wednesday while in possession of three Ceska pistols, 11 bullets and a hand grenade in Nairobi.
The arrest in Rurii’s area in the sprawling Zimmerman estate came amid heightened security after a series of attacks in the country.
Nairobi police boss Anthony Kibuchi said the suspect was handed over to the Anti-Terror Police Unit (APTU) for questioning.
The unit will seek to establish the source of the weapons and the woman's motive.
