Police have recovered all the remaining guns and ammunition stolen from Booker Police Post, Mumias about two weeks ago.
Police found the six G3 rifles and 152 bullets in a sugarcane plantation.
One of the suspects was gunned down at the plantation while three others escaped. Police have launched a manhunt for the three suspects.
One of the seven G3 rifles was recovered last week on Saturday.
Western Regional Police Commander Moses Ombati said the gun was found wrapped in a piece of cloth near river Nzoia in Mayoni.
The recovery comes amidst investigations by the Independent Policing Oversight Authority (IPOA) into alleged police brutality during an operation to recover the guns.
The Independent Medico-Legal Unit says it will ensure accountability and justice for all those who were affected by police brutality in the operation.
