A gunman hijacked a small aid plane in South Sudan and was arrested after the aircraft made a refueling stop in Wau, according to police and an aid-group statement cited by AP.

The plane was a Cessna Grand Caravan owned and operated by Samaritan’s Purse. It had departed Juba carrying medical supplies bound for Maiwut County in the far northeast. Police said the suspect, later identified as Yasir Mohammed Yusuf, snuck onto the aircraft before takeoff and hid in the rear cabin.

The man allegedly demanded that the pilot fly to Chad, a country that does not border South Sudan. The plane then circled for several hours before the pilot said it needed to refuel and landed in Wau, where police arrested the suspect. No one was injured.

The AP report says the hijacking is still under investigation and that the motive was not known. That is important because the incident could have been politically motivated, criminal or the product of personal grievance. Without a stated motive, it is safer to focus on the mechanics of the event rather than speculate.

The aircraft’s cargo also matters. Samaritan’s Purse was using it to deliver medical assistance to Maiwut County, so the hijacking disrupted a humanitarian mission as well as a flight. That makes the security breach more than an aviation incident; it touched aid operations in a region that already depends heavily on logistics.

A spokesman for police in Western Bahr el Ghazal said the suspect wore a reflective vest with an air charter company logo, though the company’s managing director said no one by that name worked for it. That detail suggests the hijacker may have tried to blend in with airport or aviation personnel.

Samaritan’s Purse thanked security forces for what it called a safe outcome. The aid group’s statement is notable because it indicates that the hijacking was resolved without injuries or loss of the aircraft. In aviation security terms, that is a best-case ending to a dangerous event.

The incident also comes at a tense time for the aid group’s operations in South Sudan. AP noted that a plane chartered by the same group crashed in Unity State on Nov. 25, killing all three crewmembers aboard. That earlier crash adds context to the risks faced by organizations moving supplies in the country.

What happened in Wau shows how fragile air transport can be in conflict-affected settings. Even a short hijacking can jeopardize a delivery mission, expose crews to danger and force authorities to respond quickly to an unexpected threat. For now, the verified facts are simple: the plane was seized in flight, diverted by force and recovered after landing for fuel.

The incident is also a reminder of how vulnerable humanitarian flight operations can be in places where security conditions are unstable. A single armed passenger, or someone who boards unnoticed, can disrupt a delivery mission and force a crew to improvise under pressure. The fact that the plane and cargo were recovered without injuries is reassuring, but the underlying risk to aid work remains clear.
