Four people have been arrested as investigations continue into the deaths of 18 elephants across the Amboseli ecosystem, with preliminary findings pointing to possible poisoning.
The elephant deaths were recorded between June 24 and July 24, 2026, in different areas of the ecosystem. The Kenya Wildlife Service (KWS) said seven cases were reported inside Amboseli National Park, another seven at Kimana Sanctuary, three in Kitenden and one at Motikanju Kuku Ranch.
Four of the seven elephants found dead inside Amboseli National Park were discovered near Kimana Gate. Investigators believe the animals may have belonged to the same herd or family, raising questions about what could have caused their deaths.
Initial laboratory results have indicated the possible presence of a toxic substance. Earlier findings had suggested cyanide poisoning after the elephants may have consumed tomatoes contaminated with pesticides from farms located near wildlife habitats.
However, authorities have cautioned that the findings are still preliminary. Further scientific tests will be carried out before a final conclusion is reached on what caused the deaths and whether the cases are linked.
The investigation is being conducted by several agencies, including KWS, security agencies, investigative authorities and scientific institutions. So far, the probe has resulted in the arrest of four persons of interest.
During a search in Tikondo, Kimana, within Loitoktok Sub-County, investigators recovered several substances that could help shed light on the deaths. The items included chemicals believed to have been sourced from a neighbouring country, potentially toxic substances and several unlabeled chemicals.
The recovered materials have been secured and submitted for scientific analysis. Authorities are seeking to establish their composition and determine whether they have any connection to the deaths of the elephants.
The Government has warned that anyone found to have unlawfully killed, poisoned or harmed wildlife will face legal action. Investigators are also expected to establish how any hazardous substances may have been obtained, handled or used.
The deaths have raised concern over the safety of wildlife living close to farms and other human activities.
The Government has said it will strengthen surveillance and law enforcement in vulnerable wildlife areas while improving scientific investigations and rapid response measures.
Authorities also plan to increase monitoring of the misuse and illegal handling of potentially dangerous substances that could threaten both wildlife and nearby communities.
Investigations are continuing as officers follow various leads to establish what happened to the elephants and whether the deaths were part of a connected incident.
The Government says those found responsible will be held accountable once sufficient evidence is established.
