Willem Oosthuizen and Theo Martins Jackson, both 28, were remanded in custody after their lawyer decided not to apply for bail.

Magistrate Jongilizwe Dumehleli said the pair should return for another court hearing on January 25.

The men face charges of kidnapping and assaulting 27-year-old Victor Mlotshwa over an incident that occurred in August at a farm near the town of Middelburg in the eastern province of Mpumalanga.

They were arrested on Monday after the video, apparently shot on a mobile phone by one of the two white men involved, went viral last week.  

The 20-second clip shows one of the assailants shoving a black man, clearly in distress, into the wooden coffin and trying to force down the lid.

“Come, come. We want to throw the petrol on,” said one of the men, speaking Afrikaans, according to the News24 website.

They are also accused of threatening to put a snake in the coffin.

Mlotshwa told ENCA television he was walking to the town of Middelburg and decided to use a short cut when the two men spotted him.

“I was in a hurry I had to use some path, a footpath, that was the shortest to go to Middelburg,” he said.

“They accused me of trespassing. Then they beat me up and I had to run away,” he said, adding he tried to flee but they caught him.

“They tied me with cable tie and took me to the nearest farm. They beat me up and forced me into the coffin.”

 -Political fury-The Economic Freedom Fighters (EFF) opposition party and the ruling African National Congress held separate rallies outside the court to protest at the alleged assault and racism in South Africa.

“We will make sure that those who are still racist, especially white people who are still racist, we will drive them to the sea so that they go back to where they come from,” ANC’s youth league deputy president, Desmond Moela, said during the rally attended by Mlotshwa.

“They want to torture our people when they are on our land.”

At another rally, the spokesman of the radical EFF Mbuyiseni Ndlozi told party members that it is “impossible” for white South Africans to see blacks as fellow human beings or as equals.

“This country has a very painful past which still seems to be our present, in which black people continue to be treated like animals.”  

“We are still in the same position we were under apartheid,” said Ndlozi.

 -Racial humiliation-Despite its long history of institutionalised racism under the apartheid regime, South Africa does not have legislation that criminalises racism though it remains beset by deep-rooted inequality 22 years after the end of white-minority rule.

Cases of racism have erupted regularly on social media in recent years.

A South African realtor was in June fined for labelling blacks as monkeys littering the beaches, after a Facebook post she put up in January.

In August, a previously whites-only girls school was ordered to suspend allegedly racist hairstyle regulations after black pupils said they had been called monkeys by teachers for wearing banned ‘afros’.
