First do not know yet what is the cause of loss so they also checked the entire building and they found a can of glue spray same as they have met before (Same brand) around the desk nearby window on 34th Floor. Moreover, they assumed that this problem occurred from the officer who put a can of spray with scotch tape and slip into window to ventilate after turning off the air conditioning system. In the same time, can of spray and scotch tape were fall down caused by the strong gust and heavy rain.
