50 arrested in slaying of Christian Pakistani couple Rights group calls it a "callous murder" Provincial government says it will give family approximately $49,000 Islamabad, Pakistan (CNN) -- Fifty people have been arrested in connection with this week's killing of a Christian couple who were beaten and pushed into a burning kiln in eastern Pakistan, a police official said Thursday. Investigators believe the 50 were part of a mob that killed the couple Tuesday after the pair were accused of desecrating the Quran, said Bin Yameen, a police official in the Kasur District in Punjab province. Police said the attack in the village of Kot Radha Kishan came after a local mullah declared the couple were guilty of blasphemy. The village is about 60 kilometers (37 miles) southwest of Lahore, the capital of Punjab. The province's government will pay the couple's family 5 million Pakistani rupees -- about $49,000 -- as compensation for their deaths, the province's chief minister, Shahbaz Sharif, said in a news release. The government also will give the family 10 acres of land, Sharif said. Rage, grief after killing of Christian couple The Human Rights Commission of Pakistan said it sent a team to the village, and that the team "did not come across any evidence of desecration of the Holy Quran." The commission said that the couple had three young children -- two sons and a daughter -- and also indicated that the slain woman was pregnant. But a postmortem examination later revealed no evidence that she was pregnant, CNN affiliate GEO News reported. Pakistan's anti-blasphemy law often is used to settle personal vendettas, rights groups say, and people accused of the committing the crime are frequently targeted by mob violence. An accusation that the couple had desecrated the Quran "was spread to nearby villages and announcements (were) made through mosque loudspeakers," the HRCP said.
