The DCI on Tuesday warned residents of Witeithie and Thika of a roaming clan of hyenas.
It was reported that a man, 29, was mauled to death by the cackle of about 20 hyenas in the wee hours of Monday morning around Kamuthi area.
He was heading home from Komu quarry and his counterpart narrowly escaped the harrowing ordeal.
Another suspected Hyena attack on a person was reported on Tuesday at Makongeni, Thika West, following a report by a resident who found a fresh human skull at his farm in Kandara Investment Scheme.
According to the DCI, a team of police and KWS officers visited the scene where they found a human skull, scattered bones and torn bloodstained clothes.
Hyena prints were also found next to the skull.
“We urge residents in the said areas to continue exercising caution and beware of the dangerous carnivores, whose attacks in their numbers are dreadful and deadly.
“Measures to hunt down and eradicate this threat is underway,” read a message by the DCI.
A multi-agency team drawn from the National Police Service, Kenya Wildlife Service and other local law enforcement agencies has been dispatched to handle the situation.
