The case in the mountainous northern region of Kohistan has attracted international attention since it first emerged in 2012, when a local cleric was accused of ordering the deaths of male and female guests filmed at a wedding.
The businessman, who was also arrested, was meant to "give the foot to a healer so that he would make a product which would make him (the father) prosperous," said the statement.
A few days ago, the father, Sarvesh spotted his daughter in a compromising position with a youth.
"The couple went to meet the parents of the woman on the occasion for Eid at a nearby location on Saturday night. They left the children at their grandmother's house and returned home. The incident happened after that," said a senior police officer.
Dr Aliza Haidar did her MRCP in psychiatry from the United Kingdom and she had married a couple of years ago. According to some media reports, Dr Aliza was the only daughter of Dr Azhar Hussain and a mother of three children.
The case has stirred public opinion since the discovery on Tuesday of the first nine bodies near the village of Baakline in the Chouf area southeast of Beirut, in what Prime Minister Hassan Diab described as an "appalling crime."
Six others accused of involvement have been acquitted, the lawyer said. They included two of Baloch's other brothers, her cousin, a neighbour, a driver, and a Muslim cleric.
"The Waziristan killings highlight how the Internet can be used against women, especially in a patriarchal society like Pakistan's," said Nighat Dad, a Pakistani lawyer who founded the country's first cyber-harassment helpline.
The police spokesperson said Aneesa Abbas, 24, and Arooj Abbas, 21, were seeking separation from their husbands and were lured back from Spain to Gujrat where they were strangled and shot on Friday night.
The ministry added that suspicions of the husband's killing swirled around his wife, who confessed after confronting her with the evidence, noting that she agreed with the so-called "Samer. S." and "Firas. S." to kill her husband.
