More than 30 Identification Cards (IDs) were found dumped on a farm just 100m from Tala Police Station in Machakos County.
It is not yet clear whether the IDs are legitimate but residents of the area are suspecting mischief.
This comes just under two weeks after the conclusion of the General Election, where members of the opposition had claimed that IDs were being issued illegally in several areas of the country to boost votes.
Earlier in the year, Amani National Congress leader Musalia Mudavadi had accused the State of selective issuance of national ID cards.
Mudavadi claimed the government was issuing IDs only in regions where there were Jubilee supporters.
He had also taken issue with the government over failure to deal with claims that there were foreigners taking part in the voter registration.
"Only Kenyans are allowed to vote. The move by the government to register foreigners with IDs and as voters will not be allowed," he said.
