The Kenya Wildlife Service (KWS) is conducting investigations in the killing of a female sub-adult rhino whose carcass was found in Nairobi National Park Sunday morning.
The rhino horns were hacked and taken away.
Last week four suspected poachers were shot dead at Solio Ranch in Nyeri and Meru National Park in two separate incidents.
Two suspects were shot dead while thethird escaped with injuries when they were found trailing a rhino at night in Solio Rhino Sanctuary in Nyeri County.
A rifle with seven rounds of ammunition and assorted poaching weapons were recovered.
In Meru National Park, a suspect was killed and four others injured when they were repulsed by KWS rangers on a mission to poach a rhino on Friday in Meru County.
One of the injured suspects later succumbed to his injuries.
An AK47 rifle, five rounds of ammunition and an axe were recovered.
KWS says its pursuing leads that will help arrest the suspects.
The new Wildlife Act, 2013 has provided for stiffer penalties for those convicted of poaching or dealing in wildlife trophies.
Poaching convicts will now face a fine of up to Ksh20 million and a life imprisonment.
