NAIROBI, Kenya- Four suspects have been arrested in connection with the deaths of 18 elephants in the Amboseli ecosystem, following a multi-agency investigation into what authorities suspect was a poisoning incident.
The investigation was conducted by the Kenya Wildlife Service (KWS), Directorate of Criminal Investigations (DCI), National Intelligence Service (NIS) and other security and scientific agencies.
According to the latest findings, the 18 elephant deaths were recorded between June 24 and July 24, 2026, across different parts of the Amboseli ecosystem.
Seven deaths were recorded inside Amboseli National Park, seven at Kimana Sanctuary, three in Kitenden and one at Motikanju Kuku Ranch.
Preliminary laboratory findings indicate that a toxic substance may have caused the deaths.
Earlier investigations had detected traces consistent with cyanide poisoning, with authorities linking the suspected exposure to substances used around farms bordering wildlife habitats.
Investigators have since expanded their probe to establish how the elephants came into contact with the suspected poison and whether the deaths were deliberately caused.
During a search in Tikondo, Kimana, in Loitoktok Sub-County, investigators recovered several chemicals and substances, including materials believed to have been sourced from a neighbouring country.
The exhibits have been secured and submitted for scientific analysis to establish their composition and possible connection to the elephant deaths.
The arrests follow weeks of investigations into the unusual deaths.
Earlier reports indicated that some of the affected elephants developed weakness and partial paralysis before dying, while others were found dead after their carcasses had been scavenged.
Most of the affected animals were adult females and calves.
The deaths initially attracted international attention after KWS launched investigations into 15 elephant carcasses found in the ecosystem.
The number later rose to 16 and subsequently 18 as additional deaths were recorded.
Amboseli is one of Kenya’s most important wildlife ecosystems and is home to a large population of elephants.
Much of the wildlife moves between the national park, conservancies and community land, bringing elephants into contact with agricultural areas.
Authorities have warned that anyone found responsible for unlawfully poisoning or killing wildlife will face legal action.
Investigations remain ongoing, with detectives pursuing additional leads to determine the source of the suspected poison, how it was administered and whether more people were involved.
