More than 10 people were killed when activists of Pakistan Awami Tehreek (PAT) clashed with Punjab Police on 17th June 2014.
PTI Chairman Imran Khan, in his message on social media website Twitter, tweeted that absolving Rana Sanaullah and Shahbaz Sharif is the height of injustice.
The acquittal will encourage the police to resort to same action with impunity in the future.
Shocking: Model Town massacre JIT absolved CM & Rana Sanaullah. Height of injustice. Message to police is they can do it again with impunity
