Lawyers now want two other people who mysteriously disappeared be produced by the state.
LSK sued the government over their disappearance on an unspecified date in June.
Brian Nzeze and Aluda Mambo, reportedly went missing after being arrested at about 4pm in Kawagware, Nairobi.
Documents filed in court indicate the boda boda rider and his passenger were bundled into a Land Rover GKA875X and driven off to an unknown destination.
According to the papers, they were then taken into custody by AP officers attached to the Kawangware chiefs camp.
LSK said the unexplained disappearances have caused parents and relatives untold agony, emotional distress and suffering.
This comes in the backdrop of a report that indicated Kenyan security officers have secretly abducted at least 34 people in the last two years during abusive counter terrorism operations.
