Five people arrested in the public stoning death of a pregnant Pakistani woman will be taken to an anti-terrorism court , authorities said . Farzana Parveen , 25 , was killed in Lahore because she married a man against her family 's wishes . Police arrested her father , her uncle , two cousins and the driver who brought them to Lahore , said Zulfikar Hameed , the lead investigator in the case . The court is treating the act as an act of terror that has `` wider consequences on the safety and well being of all of society , '' according to lawyer Maliha Zia , who works for Aurat Foundation , a Pakistani women 's rights organization . She said she was worried that international pressure may have forced the government to convene an anti-terrorist court in an act of `` show and tell . '' `` I hope that the quality of the trial does not go down if it 's sped up , '' she said . `` The investigation does not suffer and the trial does not suffer because of the shortened time period . What I 'm hoping for is a better quality trial . '' Pakistani police officers will be investigated because they did n't intervene when Parveen was publicly beaten to death with bricks , a court official said . Prime Minister Nawaz Sharif on Friday called the killing `` totally unacceptable '' and said it 's a `` great shame '' for such a crime to happen in the presence of police . About 20 people , including members of Parveen 's immediate family , attacked her with bricks Tuesday outside a court building in Lahore , police said . Such killings not uncommon . Such killings often originate from tribal traditions in Pakistan but are not a part of Islam . They usually happen in rural areas , not large cities such as Lahore . Human rights activists said bystanders , including police , often do n't intervene because the killings are considered family matters . The Human Rights Commission of Pakistan said 869 women were victims last year ( PDF ) in the nation of about 180 million people . They are sometimes called honor killings because the women are accused of bringing dishonor upon the family by having an adulterous affair , being raped or wearing clothes considered revealing . Women 's rights advocates say the actual number may be much higher . The United Nations estimates that at least 5,000 women worldwide die yearly in such killings . The prevalence of violence against women in Pakistan became apparent Thursday when Parveen 's husband , Mohammad Iqbal , revealed to CNN that he killed his first wife six years ago so he could marry Parveen . His son said Iqbal served a year in jail . Iqbal , a neighbor of Parveen 's family , said he and Parveen were supposed to marry with the family 's approval last year . In December , her father and brothers decided Parveen , who came from a village in Punjab , should instead marry a cousin , police said . Opinion : How stoning of a woman riled the world . Bride 's family infuriated . Parveen and Iqbal eloped and were married January 7 in a court ceremony . But Iqbal told GEO TV that Parveen 's family was infuriated and filed a kidnapping case against him and other members of his family . They also demanded 100,000 rupees ( about $ 1,000 ) , he said . The couple went into hiding and filed statements in court to prove the kidnapping allegations false , Iqbal said . On Tuesday morning , they were scheduled to appear before a judge when Parveen 's family allegedly attacked outside the court building . `` We went to the court to seek justice to tell them what had happened . We were sitting there when all of a sudden they appeared , '' he told GEO TV . `` Someone fired shots in the air . My wife and I were sitting , and then bricks were thrown . Then a lady came and took Farzana away . '' Police stood and watched and did n't come to their aid , Iqbal said . He said the crowd killed his wife and her fetus . In addition to the prime minister , other officials rushed to denounce the killing . The chief minister of Punjab , Shahbaz Sharif , gave a 24-hour ultimatum to the inspector general to arrest the suspects . He asked that a murder trial be held in an anti-terrorism court . Britsh Foreign Secretary William Hague said , `` There is absolutely no honor in honor killings , and I urge the government of Pakistan to do all in its power to eradicate this barbaric practice .
