Window cleaner pictured balancing 100ft above Manhattan streets as he works WITHOUT a safety harness The unknown workman was pictured with no safety equipment as he cleaned the tenth floor windows Onlookers saw him shuffle from window to window before casually dropping inside when he was finished A window cleaner took his job to extreme levels when he was pictured working ten storys high without a safety harness. The daredevil workman had nothing to stop him falling 100ft to the ground as he shuffled from window to window at the New York office block. Passers-by watched from the Manhattan street below and from neighboring buildings as he fearlessly perched on the ledge with not even a rope to protect him. Don't look down: The window cleaner perches on a ledge as he works without a safety harness 100ft above the ground Daredevil: The window cleaner was working on the tenth floor of the office block in Manhattan, New York, when he was pictured The unknown workman was seen climbing out of an open window and holding onto just the wall for support. When he was finished with one window, he shuffled along the outside of the building to wash the next. Once he had moved onto third, he was seen casually dropping his tools back inside before ducking inside and closing the window behind him. People on the street below were seen pointing at the sky as he nervelessly worked. Disbelief: Onlookers said they were horrified to see him working so high up without a rope and said they feared he was 'pushing his luck' Death-defying: Witnesses said he moved confidently from window to window before casually dropping back inside when he was finished His death-defying journey took place on Thursday just yards away from office staff busy at work, completely unaware of what was happening behind them. One onlooker said they were shocked that anyone would risk their life in such a way. They said: 'I was on my way back from a meeting and saw people pointing towards the sky - I couldn't see what was happening at first because the buildings are so tall. 'But through a small gap I could see this guy hanging onto the wall and washing windows, the other people watching told me he didn't have a rope. Vertigo: Passers-by in Manhattan spotted him from the street and could be seen pointing at the sky in disbelief at how he was working Quite a drop: The unknown cleaner had no protection if he had slipped while shuffling between the windows ten storeys up I have never seen anything like it before. It was actually pretty hard to watch because I was thinking to myself what happens if he slips. 'I'm not sure it's worth it just to finish the job a bit faster. He moved confidently enough so I assume he's done it before - you wonder how long he can keep pushing his luck for.' The management or a health and safety spokesperson for the building was not immediately available for comment.
