Mardan RPO Alam Khan Shinwari submitted the report in the apex court.
Earlier on Monday, Inspector General Police (IGP) KP Salahuddin Khan Mehsud reaffirmed during a press conference that no concrete evidence of blasphemy was found against the slain Abdul Wali Khan student Mashal Khan and his surviving colleagues Abdullah and Zubair.
“I will ensure that the investigation is impartial,” he assured reporters. “Details of the incident will be submitted to the Supreme Court [on Tuesday]. It will contain all major and minute details of our investigation.”
Mashal Khan was lynched at his university campus premises on April 13 by an angry mob that accused him of committing blasphemy while another student Abdullah was injured.
A police spokesperson disclosed earlier that the suspects were identified through closed-circuit television (CCTV) cameras. 22 individuals including six employees of the university have been arrested in the murder case so far.
"The suspects will be presented in an anti-terrorism court."
