It is claimed Aqeel Masih, who worked at a petrol pump in the city of Lahore, was kidnapped by a group of religious fanatics and left permanently disfigured on June, 24.
The Legal Evangelical Association Development (LEAD), a Christian organisation operating in Pakistan, said: "[Aqeel] revealed that the extremists exerted pressure on him to abandon Christianity and convert to Islam.
"Aqeel however, did not give up on his Christian faith and refused to comply with their demand. Notwithstanding, his rebuttal, they chopped off his both arms, and absconded."
It is claimed Mr Masih has filed a lawsuit against the people allegedly behind his disfigurement but his claims have already purportedly met resisted from police.
A senior police investigator told The Nation newspaper in Pakistan three suspects are detained in connection with the incident, however: "The circumstantial evidences do not support the claims of the victim.
"Apparently, it seemed that the man lost his arms in a train accident,"
Officers reportedly claim he has been addicted to drugs and lost his arms by getting too close to a train during an overdose.
Upon his arrival at Ghalib Market Police Station on Tuesday, police tried to stop Mr Masih speaking with members of the media, the LEAD claimed.
