Two Kenya Defence Forces (KDF) soldiers were at the weekend arrested and four flash grenades found on them after a dramatic confrontation in a bar in Sotik, Bomet county.
They were found with four NF24 48mm sound grenades, police aware of the incident said.
They had also used two others in a bar where they were, police said.
Residents had complained there were loud bangs at Chebole trading centre, which they believed were explosions.
The residents said the suspects were seen heading towards a bar in the area amid tension.
Police rushed to the scene where two soldiers based in Modika military base in Garissa, were arrested.
A search conducted in the bar recovered two grenade pins suspected to be from the grenades that caused the explosion in the Friday incident.
A further search was conducted on their bags and the four sound grenades were recovered amongst other personal effects, police said.
The two were detained at the local Mutarakwa and officials from the military police alerted to pick them up for action.
Military personnel cases are at times handled by the military police. It also depends on the nature of the case.
For the case of handling the explosives, police said they will jointly handle the matter with the military personnel.
Officials said they want to understand why the personnel decided to travel to their rural homes with the explosives.
One officer said they suspected the two were out for a show, which went bad.
Elsewhere in Cheptulu, Vihiga county, a police officer was arrested for attempting to obtain money from a vet dealer in the town.
Another officer managed to escape from the scene after police were called, police said.
They had presented themselves as vet dealers and wanted money for goods supplied there when the owner called for help from police.
When police arrived at the scene, the officers first claimed to be from Narok and when the authorities in Narok were contacted, they denied their knowledge.
It was then that one officer sneaked out and escaped the scene using a car they had.
It was later established the officers are from Suneka, Kisii county.
Police said they are trying to trace the one who escaped the scene on November 11.
The investigators also want to establish if the men have been involved in other crimes in the area and other places.
Cases where police are involved in crime have been on the rise. Police authorities say the cases are under probe.
