A group of human rights lawyers in Warri, southern Nigeria, is seeking compensation for four hotel workers who were allegedly stripped naked by their employer.
They had been accused of stealing some money, but local media are reporting that they had been tipped by some guests.
The four, three women and a man, were allegedly ordered to undress and were left wearing only their knickers or underpants as others, including the police, looked on.
Photos and videos of the victims standing nearly naked were taken and shared widely on social media.
The lawyers have written to the hotel owner - a former Nigerian minister - threatening legal action over the violation of the privacy and dehumanisation of their clients.
They are asking for compensation and a public apology.
The victims said that the photos and videos were shared on the internet to humiliate them.
