Kenya Wildlife Service (KWS) rangers are pursuing poachers who killed a black rhino at the Aberdare National Park in Nyeri.
The three-year-old rhino had its horn sawed off in the Sunday night incident and the carcass was discovered on Monday afternoon.
The park now has only six black rhinos left alive.
Authorities say that a gunshot was heard coming from inside the park prompting an overnight patrol by KWS rangers.
POACHERS AT LARGE
KWS Assistant Director Simon Gitau told the Nation that the overnight search did not yield any results in tracking down the poachers or rhinos.
"The matter is under investigation," Mr Gitau said.
