**Malkangiri:** Tension prevailed at a fuel filling station on Wednesday evening here at the district headquarters town when the vehicles developed snags soon after being refilled with diesel as water was amazingly discovered instead of diesel in their oil tanks.
Rushing back to the filling station they found that the underground diesel tank of the filling station was oozing water-adulterated diesel following which tension prevailed there.
As per reports, the queer incident occurred at Sivam Filling Station near the bus stand here.
While the Civil Supplies officials have collected sample and sent for testing in the laboratory to ascertain adulteration, the owner has been barred from selling diesel till the test report has come.
On the other hand, the filling station owner defended that it was due to the heavy rains as the iron cap of the underground diesel tank was found being rusted causing the rain water to sip into it.
