One of the men who helped bury the Abba Kyari, the late Chief of staff to President Muhammadu Buhari was seen in a viral video pulling off and dumping his protective clothing in the public.
Many Nigerians are calling the Nigeria Centre for Disease Control to take action.
Mr Kyari died on Saturday at a private clinic in Lagos State where he was treated for COVID-19 complications.
The federal government flew his remains to Abuja on Saturday for burial.
He was buried yesterday by several men wearing white protecting clothing and closed family members.
Immediately after the burial, a video was posted online showing a man pulling off his protecting clothing beside a car.
He later put the white clothing in a red polythene bag and dropped it by the side of the road.
Many Nigerians have expressed concerns over his actions and called on the government to take action.
