They were sentenced to two years imprisonment and fined Rs 50,000 each.

After the completion of their sentence, they were released from Mianwali's district jail and returned to their hometown, to the shock and outrage of residents.

The duo had spent most of their two-year prison term in King Edwards medical college Lahore, where they were being examined by the neurophysiology department, the report said.
