On February 8, members of several hard-line religious parties, including Jamaat-i Islami and Jamiat Ulema-i Islam, showered those acquitted with rose petals and labelled them as "heroes".
Muhammad Asif Khan, vice-chancellor of the University of Peshawar, told University World News: "We welcome the court verdict against the inhumane killing of an innocent student but all those spotted in a mobile phone video of the mob who lynched Mashal must be punished".
According to media reports, members of religious parties welcomed the release of 26 people acquitted by an anti-terrorism court in the murder of university student Mashal Khan.
