Four ISIS militants dressed in white robes and black tactical vests, stand in a line as a judge reads out the statement condemning the man to his death.
The announcement is done over a microphone system in an attempt to maximise publicity about the shocking abuse of human rights in the city.
The crowd appears to be predominantly made up of militants, many carrying their weapons and wearing their uniforms.
Standing near the front of the crowd, a number of children can be seen waiting for the punishment, each dressed in military style thobes.
Unusually, ISIS have not published photos of the moment the man is pushed off the building. Instead the final image embodies the heinous nature of the bloodthirsty jihadi group.
Photographed from the top of the building from which he was pushed, the man's crumpled body lies motionless on the hard tarmac.
The news comes as ISIS faces increased military threat from Turkish forces after the government stated plans to create a buffer zone along the border.
Turkish fighter jets carried out a round of air strikes on ISIS positions in Syria and Kurdish (PKK) militant bases in northern Iraq.
The moves by Turkey come after tensions came to a head following the deadly suicide bomb attack on a pro-Kurdish demonstration in Suruc, near the Turkish-Syrian border.
32 activists were killed in the blast at the small Turkish town, leading to claims that the bomber may have been sent by ISIS. Unusually, no group has claimed responsibility for the attack.
