Ghost CCTV Balloon

Is this a ghost pulling the balloon down and walking with the balloon? This is one of 2 CCTV footage recorded in Chapelfield Mall, Norwich, UK, think of the physics of a balloon and how they move \ float etc. Could be coincidence however there was no breeze or air con in the building and the escalators were switched off which would prevent any draft. Watch and tell me what you think! The mall is known to be haunted.
