The lynching of Dipu C. D, initially reported to be over blasphemy, is now believed to stem from workplace tensions after he was fired from his job.

Shocking findings into the death of Dipu, a worker whose body was set on fire after being lynched in Bangladesh last week, has led to a chilling twist in the incident that was first reported to have taken place due to “blasphemy” by the 27-year old victim.

He was lynched by a mob in Mymensingh city on Thursday amid a fresh wave of unrest following the death of student leader Sharif Osman Hadi, who was a prominent face in the anti-government protests that forced the collapse of the Sheikh Hasina government.

Gut-wrenching videos purportedly showing him being beaten to death by a mob that accused him of blasphemy and his body being tied to a tree and set on fire.

Family of the victim, who worked at Pioneer Knitwears (BD) Limited - said tensions escalated inside the factory earlier that day, according to the report, and added that he had recently attempted a recruitment examination for promotion from floor manager to supervisor.

His brother told that Dipu had disputes with several colleagues over his position.

On December 18 afternoon, he was sacked from his job, shortly after which allegations of insulting religion were levelled against him – claims that police said are not backed by any evidence.

"They beat my brother and threw him out of the factory," Dipu's brother was quoted as saying.

"Even after he was caught and apologized, they did not spare him," he added.

Dipu had long-standing disputes over production targets, overtime, working conditions and workers' benefits, a conspiracy gradually formed to remove him from the factory," he was quoted as saying.

Dipu was beaten about a kilometre from the factory before his body was tied to a tree and set on fire.
