Nigeria, Feb. 23 -- Police officers in Aba, Abia State, have been caught on camera using a machete to flog a resident.

A video posted on Twitter, on Tuesday, by Harrison (@harrisonmbamara), showed four police officers forcing a man and a woman to do 'frog jumps' in the middle of a quiet road.

The man was later asked to lie down on the tarred road, while an officer used a machete to flog him repeatedly.

The officers could be heard, from the clip, shouting at their victims who appeared helpless.

It is unclear why the two were being punished.

But from the voices from the background, from the people who were doing the secret recording, it appeared the assault was linked to the Tuesday attack on a police station in the city.
