The Minister of Home Affairs, Immigration, Safety, and Security, Lucia Iipumbu, said a Quantum bus was available for the Namibia Correctional Service officials who died in the Mariental accident on Saturday.
She said it remains unclear why the officers were transported in a vehicle reserved for inmates.
Iipumbu, alongside the Police Chief and the Commissioner General of the Namibian Correctional Services, held a press conference in Windhoek on Monday.
She said the ministry has dispatched various experts, including psychologists, to assist the grieving family members.
She explained that investigations are ongoing and informed the briefing that four officers remain in hospital in critical condition and are unable to provide clarity on why a decision was taken to transport the staff to their place of work in a vehicle normally reserved for inmates.
NBC News has reliably established that a NamPol officer was discharged on Sunday.
The police chief, Lieutenant General Joseph Shikongo, said the two civilians were assisted by the police and were being transported to the hospital.
The accident occurred five kilometres outside of Mariental between six and seven o'clock in the morning.
The total occupants in both vehicles were 20.
