The arrests followed a formal complaint lodged by SHA after a forensic audit uncovered widespread irregularities in medical claims submitted by several contracted healthcare providers. Subsequent investigations established that the suspects orchestrated fraudulent schemes involving irregular and fictitious medical claims, including claims for patients who were never admitted, falsified medical records, and false statements used to obtain payments from SHA. Investigations revealed that Nissi Medical Centre received more than Ksh 38.7 million through fraudulent claims, while Dawa Front Healthcare Services is suspected of fraudulently obtaining more than Ksh 2.5 million. Detectives also intercepted additional claims worth more than Ksh 8.1 million before they could be paid. The five accused persons are Nissi Medical Centre directors Dominic Atieno and Peter Atieno, and Dawa Front Healthcare Services directors Eugine Ochieng, Enos Osire, and Elija Otieno.
