Islamabad, Sep 25 (IANS): The Pakistan Supreme Court on Wednesday acquitted a blasphemy accused who was earlier sentenced to death by the trial and high court, after nearly two decades.

The apex court, in its judgment, observed that the prosecution failed to prove the case against the accused, Wajeehul Hassan, who had earlier challenged his conviction, The Express Tribune reported.

Hassan was accused by a lawyer in 1998 for writing blasphemous letters to him.

During the hearing, Justice Sajjad Shah observed that the prosecution had failed to prove that the letters were written by Hassan and dismissed the case.

The Supreme Court last year acquitted Aasia Bibi - a Christian woman accused of blasphemy in 2010 and sentenced to death - and set aside an earlier judgment passed by a lower court.

The 51-year-old Christian woman was on the death row since November 2010 after she was convicted on charges of committing blasphemy during an argument with two Muslim women in Sheikhupura.
