Error! CCTV captures man walking through glass window

The ill-fated moment a security guard walked straight through a glass window pane during a night shift has been caught on CCTV.
The short clip, which has gone viral on the Web, shows the man disregarding a wide-open door and mistakenly walking straight through a glass window pane instead - shattering it completely.

Realising the massive error, he clutches his face in agony while the whole glass pane crashes down behind him. He then proceeds to kneel to the floor in pain.

Luckily for him, a pair of smartly-dressed men come to his rescue and check whether he’s OK.

We really hope the man in the video recovered after the unfortunate accident. It may have just been a long day at the office or the glass was very weak.
