Kathmandu — Nepal Police arrested six people as part of an investigation into alleged fraudulent helicopter rescue operations in the Everest and other high-altitude trekking regions.

In a statement issued by the Central Investigation Bureau (CIB), police said the suspects are accused of arranging helicopter evacuations that were presented as medical emergencies, despite not meeting the required medical criteria. Authorities allege the practice was used to generate inflated insurance claims, primarily involving foreign trekkers and mountaineers.

Police identified those arrested as Kumar Pasang Sherpa, Mingma Sherpa, Nima Sherpa, Pemba Sherpa, Nima Wangchu Sherpa, and Mingma Gyalzen Sherpa. According to investigators, the individuals are linked to companies involved in trekking services, rescue coordination and helicopter charter operations.

The CIB said the investigation found evidence suggesting that false medical documentation — including hospital admission and discharge reports — was used to justify emergency evacuations. Police warned that the misuse of rescue services risks diverting helicopters and medical resources away from genuine life-threatening emergencies in Nepal’s remote mountain regions.

Authorities also said such practices could undermine Nepal’s reputation as a leading global destination for trekking and mountaineering. The police statement described the alleged activity as harmful to both public safety and the integrity of the tourism sector.

The six individuals are being investigated under Nepal’s criminal and financial fraud laws. Police said further arrests have not been ruled out as the investigation continues.

Concerns over the regulation of helicopter rescues in Nepal have been raised repeatedly in recent years. Tourism experts and insurers have previously warned that weak oversight, combined with high insurance payouts, may create incentives for unnecessary evacuations.

Tourism authorities said rescue coordination procedures are under review, while insurance companies have been urged to strengthen verification processes before approving evacuation claims.

The government has reiterated that legitimate helicopter rescues remain vital in the Himalayas, where rapid evacuation can save lives. Officials have stressed that Nepal remains a safe destination for trekkers and climbers.

Police said the investigation is ongoing.
