Five hyenas believed to have eaten about 260 goats in Hola have been killed. The beasts also attacked a woman and her son in Haroresa and Wayu locations two weeks ago.
The acting Kenya Wildlife Service warden in Tana River, Mr Alio Adan, said the animals were trapped following a public outcry.
He said the operation to eliminate the rogue hyenas was still going on in all affected areas.
He said the woman and her 14-year-old boy were severely injured by the animals that had attacked goats in their homestead.
The two were treated at Hola district hospital and discharged.
Mr Adan said elephants which had invaded irrigation scheme farms had been chased away and were now in Kora game reserve, Merti district. (KNA)
