Mr Mengal was reportedly killed by drug peddlers last year.
Members of civil society, students, teachers and political workers participated in a walk organised by the Baloch Students Action Committee and Nushki Online to mark first death anniversary of Sami Mengal, who was a student of Balochistan University’s Zoology Department.
Addressing the walk participants, Professor Ghulam Dastgir Sabir, Aziz Jamaldini, Ghamkhwar Hayat, Abdul Wajid Mengal, Tayyab Yallanzai and others paid tribute to Sami Mengal for his struggle against widespread business of drugs in Nushki and surrounding areas.
They said drug smugglers killed Sami Mengal in front of his mother. They regretted that despite constant protests culprits had not yet been arrested.
