Islamabad/Washington, June 14 (ANI): Family members of a young Christian man have claimed that he was raped and brutally murdered in Pakistan because he refused to convert to Islam.

According to a Fox News report, the victim's brother said police found 28-year-old Tariq "Litto" Mashi Ghauri, a university student in Sargodha, Pakistan, lying dead in a canal outside a village in Punjab Province on May 15.

He had been raped and stabbed at least five times.

"They have sexually abuse him, torture him with a knife on his testicle and genitals," Ghauri's brother, 24-year-old Salman Nabil Ghauri, said.

The family believes brothers of his Muslim girlfriend, Shazi Cheema, killed Litto after they found him in a compromising sexual position with their sister.

The Rev. Haroon Bhatti, a Christian clergyman in the village and a friend of the Ghauri family, said Cheema's three brothers came to Litto Ghauri's house on May 11 and gave him an ultimatum: Marry their sister and convert to Islam.

Ghauri agreed to the marriage but refused to accept Islam, and the brothers kidnapped him at gunpoint and drove him to a remote farmhouse, where they tortured and murdered him, the minister said.

After police discovered the body, Ghauri's death was declared a homicide and the family filed paperwork with the Atta Shaheed police station in their small village, Adda 44SB.

But Ghauri's brother said police still have not arrested the alleged killers and have refused to meet with his family.

The Pakistani Embassy in Washington, D.C., told FOXNews.com that they knew nothing of the incident but were looking into it.

"If an incident of that nature happened over there, there would have to be an investigation," an embassy official added. (ANI)
