A bodaboda rider died after he was hit by a lorry in Kambi ya Juu on the outskirts of Isiolo town.
The speeding lorry was heading towards Burat to collect murram when it lost control and rammed into the rider, who was ferrying crates of tomatoes to Isiolo market, killing him on the spot.
The driver immediately fled from the scene after the Sunday incident, forcing the highly charged public to torch the lorry despite a huge presence of police officers in the area.
Another person, reported to be a relative of the owner of the lorry, was beaten up and seriously injured by the angry mob and left at the scene. It is said that he later died although authorities insisted that the incident was not reported.
Police officers were forced to use tear gas to disperse the rowdy protesters who engaged them in running battles for the better part of the day, paralysing services on the busy road.
A county fire engine that had gone to put out the fire was forced to turn back after the irate residents started pelting it with stones.
Stephen Mbaabu, the area manager, said the protesters had, before setting the lorry ablaze, confronted the police officers demanding to know the owner of the vehicle.
Isiolo Sub-County Police Commander George Kariuki said investigations are underway and that the driver of the lorry, who is still at large, is being pursued.
Five other residents, whom police officers identified as having set the vehicle on fire, are also being sought.
“We are hunting down the driver and the five residents identified by our officers as having torched the lorry,” said Mr Kariuki.
