Another video shows what seems like his lifeless body being carried by the limbs by his attackers.
Another friend of Themane's took to his Facebook account to say he was in disbelief about his passing and expressed pain in the manner in which he died.
Limpopo man 'beaten to death' would never have hurt anyone, say his friends
Friends of the man who was beaten to death and dumped in Flora Park, Polokwane, at the weekend on Tuesday expressed shock and dismay at the killing.
The friends paid tribute to Thoriso Themane, who was alleged to have been beaten by a group of people. At least one learner from Capricorn High School is alleged to have been in the mob.
Police have reportedly visited the school.
The Limpopo education department expressed shock at the allegations that a pupil was involved.
"The Limpopo department of education is deeply horrified and saddened by allegations of murder in which a Capricorn High learner is said to be a suspect," said spokesperson Sam Makondo. "The incident has been captured on a video which has since gone viral. The suspect has today been taken in for questioning by the police."
Makondo said they did not immediately have the details of the incident, but a psycho-social team had been deployed to the school to provide counselling for learners.
A former classmate of Themane's said that she was hurt by the manner in which he is believed to have died.
"We went to Flora Park Comprehensive high school and matriculated in 2011 together. He was the class clown who made everyone laugh," said the woman, who asked not to be named.
"I hated the school but he made thing better," she added.

Meanwhile, his former classmate said: "I am in shock. Angry and hurt at the same time. He was a good guy and would have never hurt anyone."
Police reportedly went to Capricorn High School on Monday in connection with the incident.
This came after another video surfaced showing a boy in school uniform being asked if he feels good about killing a person. The boy says yes because he knows that nothing will happen to him. The short dialogue happens in Sepedi.
Asked how she felt about the allegations that Themane's killers could be children, the former classmate said: "I think they should serve their time. They know what is right and wrong - they know there are consequences for their actions. The fact that they are minors cannot be used as an excuse."
Meanwhile, another friend expressed how Themane had escaped a near-death experience last year.
