Two traders were robbed of Sh1.8 million in separate incidents in Kakamega town on Tuesday.
In the first incident, an employee at a shop in Kakamega town was robbed of Sh1.2 million on his way to a bank.
The worker told police he was kidnapped by armed men, who bundled him into a vehicle on Tuesday.
Western region police chief Moses Ombati said the gangsters escaped after abandoning the worker in Malava town.
A trader was also robbed of Sh600,000 at a supermarket in Kakamega.
Three men armed with a gun snatched the money from Mr Sachin Parajabata shortly after he closed the Maisha Mart Supermarket on Maziwa Road at 9 pm.
The gangsters shot three times in the air before escaping on a motorcycle.
Mr Ombati said no one was injured in the incident.
“We have launched investigations after the trader reported the robbery which happened next to the busy market,” he said.
He said the trader had asked police officers, who were guarding the premises to be withdrawn without giving an explanation.
“We have advised supermarket owners in Kakamega County to have police officers deployed to guard their business premises and it is strange that the trader decided to have the officers withdrawn from his supermarket,” said Mr Ombati.
