A man previously arrested for digging up bodies and eating them was arrested again after authorities in Pakistan said they found the head of a young child in his home.

The BBC reports that convicted cannibal Mohammad Arif Ali was taken into custody on Monday morning after police in Darya Khan, Pakistan, raided his home following reports of a bad smell emanating from the residence.

"We found the severed head of a young child, about 2 or 3 years old," Ameer Abdullah Khan, superintendent of police in Darya Khan, said. "They probably dug up his body from a grave, but the identity of the child and the graveyard from where his body might have been stolen is not clear."

The Express Tribune reports that Arif Ali and his brother, Mohammad Farman Ali, were imprisoned in 2011 for digging up as many as 150 bodies and eating their flesh. They were both sentenced to two years in prison.

Farman Ali is also wanted in connection with the latest incident.

"I'm not a doctor, but these guys are trouble," Chief Constable Zafar Iqbal of the Bhakkar Police said, according to NBC News. "They've served time before. Maybe they have psychological problems, or maybe they're just bums. No wives, a family that doesn't talk to them, and a community that shuns them."

NBC News also reports that Arif Ali was charged with various crimes, including terrorism.
