In December 1999, Iqbal sent a letter to police and a local Lahore newspaper confessing to the murders of 100 boys, all aged between six and 16. In the letter, he claimed to have strangled and dismembered the victims - mostly runaways and orphans living on the streets of Lahore - and disposed of their bodies using vats of hydrochloric acid. He then dumped the remains in a local river. In his house, police and reporters found bloodstains on the walls and floor with the chain on which Iqbal claimed to have strangled his victims, photographs of many of his victims in plastic bags. These items were neatly labeled with handwritten pamphlets. Two vats of acid with partially dissolved human remains were also left in the open for police to find, with a note claiming "the bodies in the house have deliberately not been disposed of so that authorities will find them."[1]
Iqbal confessed in his letter that he planned to drown himself in the Ravi River following his crimes but after unsuccessfully dragging the river with nets, police launched what was, at that time, the largest manhunt Pakistan had ever witnessed. Four accomplices, teenage boys who had shared Iqbal's three-bedroom flat, were arrested in Sohawa. Within days, one of them died in police custody, allegedly by jumping from a window, though a post-mortem suggested that force had been used against him.[2]
It was a month before Iqbal turned himself in at the offices of the Urdu-language newspaper Daily Jang on the 30th December, 1999. He was subsequently arrested. He stated that he had surrendered to the newspaper because he feared for his life and was concerned that the police would kill him.[1]
Although his diary contained detailed descriptions of the murders, and despite the handwriting on the placards in his house matching Iqbal's, he claimed in court that he was innocent and that the entire affair was an elaborate hoax to draw attention to the plight of runaway children from poor families. He claimed that his statements to police were made under duress. Over a hundred witnesses testified against Iqbal and he and his accomplices were found guilty.[citation needed]
Iqbal was sentenced to death by hanging.
