The officers accessed the surveillance room and watched the video about everything that happened few minutes before the incident.
First, they saw the young man walking in after kissing a female worker at that door then there was a point when he took out his phone and started watching and then right up to the moment that he yelled about his phone switching off even when it was hundred percent charged just a few minutes ago.
Then they noticed a hand appearing out of thin air and grabbing the small camera at the table then came the drama from the expression changes of the young camera man and then came the moment where the bigger camera was taken into thin air by the same hands.
The same hand appeared once again and jabbed the neck of the young man and he collapsed then the appearance of the same hand once again grabbing the young man into thin air.
