Two prison wardens yesterday were charged with having ivory worth Sh500,000.
Paul Mwangi and Lawrence Kinoti denied having the ivory in Nairobi West on Tuesday.
They were also charged with dealing in wildlife trophies without a permit from the Kenya Wildlife Trophies.
They appeared before Kibera senior principal magistrate Elizabeth Osoro and pleaded for reasonable bond terms.
Police reports said the officers got a tip from the public about people with the illegal tusks.
A trap was laid and police arrested them.
They were each released on a Sh500,000 bond.
The case will be heard on September 16.
