LAHORE: Two brothers who were earlier sentenced for eating five corpses dug out from a graveyard of the Darya Khan locality in Bhakkar district have again been found involved in cannibalism, DawnNews reported.

Police arrested one of the brothers, Mohammad Arif, on Monday and found a child's body parts at their residence. The other brother, Mohammad Farman, managed to flee before he could be detained.

Arif, previously convicted over cannibalism, was arrested today after police found a young boy's head in his home. Police said Arif confessed to eating human body parts during interrogation.

The two brothers, Arif, 35, and Farman, 30, from the small town of Darya Khan, had dug up more than 100 corpses from the local graveyard and eaten them in the past, police said.

"Residents informed police after a stench emanated from the house of the two brothers. We raided the house on Monday morning and found the head of a young boy," district police chief, Ameer Abdullah, told Reuters.

"We have arrested one of the brothers, Mohammad Arif, and are conducting raids for the arrest of the other brother."

Police were searching nearby graveyards to see if they had been disturbed, he said.

Arif and his brother were sentenced to two years imprisonment after they were found engaged in cannibalism and were released only last year.

Taking notice of the incident, Punjab Chief Minister Shahbaz Sharif called for a report from DPO Bhakkar.

Farman and Arif were first arrested for cannibalism in 2011 and the town had attracted both national and international media coverage when on April 3 that year, the newly-buried body of a girl was found in their house with a few limbs cooked in a curry.
