A Machakos County businessman was found dead inside his car, with his hands tied to the driver's seat, in Masinga Sub-county on Wednesday night.
Police identified the victim as 53-year-old businessman Peter Mwangangi Mula, who owned REXX Bar in Kanyoonyoo near Matuu town.
They suspect he was injected with a lethal substance.

His body was discovered at about 9pm at Kwasuvu Village in Mikuyuni Sub-location, Kangonde.
"It was established that on [Wednesday] between [3pm and 4pm], Mr Mula was with his friends taking beer [in his bar at] Kanyoonyoo market centre.
