The body of a middle-aged man was on Wednesday retrieved under a tunnel dug on the Kenya Pipeline Company (KPC) fuel line.
This was the second body to be retrieved from the tunnel after police discovered a fuel siphoning racket from members of the public.
The body was discovered when the KPC emergency team were digging to establish the source of fuel siphoning for repairs.
It was found inside the tunnel dug by the suspects along the Nakuru-Kisumu line.
Kisumu County Police Commander Alphonse Wambua confirmed the incident, saying the body has been taken to Jaramogi Oginga Odinga Teaching and Referral Hospital (JOOTRH.
An unidentified body of a man was also retrieved from the tunnel on Tuesday.
The joint operation by KPC engineers, police and firefighters has been completed today, with several litres of the super petrol in the septic tank drained.
No arrests have so far been made in connection with the illegal racket.
