Mushtaq Ahmed Baloch, 22, who was already married and was had children, was having an affair with his cousin Rani Bibi, a mother of two, and came to her house at night while her family was sleeping, police said.
The noise as Baloch entered the house woke up Bibi’s father and brothers-in-law, which prompted her to hide him in a large tin storage trunk in her room. She then placed a padlock on the trunk.
Her in-laws came to search the room and Baloch was forced to cry out for help as he was suffocating, police said. They did not open the trunk and he died within 15 minutes, police added.
The incident took place in the suburbs of the central town of Muzaffargarh, late Saturday night.
“We have arrested Bibi’s father-in-law and his two sons on murder charges,” said local police station chief Sardar Muhammad Idrees.
He said that Bibi’s husband was not at home as he had a job in the southern port city of Karachi, some 900 km (550 miles) away. Muzaffargarh district police chief of Awais Ahmed Malik confirmed the details.
