This was surely a bad day in the office for a circus manager as he was almost turn into shreds by his lion.

Why the lion got so upset to the extent of attacking his trainer is still a mystery.

Ordinarily one would have thought the lion must have been well trained in the act of circus tricks before being displayed.

Perhaps the lion did not complete the training exercise.

A video of the sad scene captured by a woman, Sevda Binici, in the audience showed the lion grappling with the trainer before being subdued, allowing the trainer to escape.

The video posted by Storyful, also showed the audience swiftly dispersing after the accident.

According to reports, the trainer, Steeve Loberot, was badly wounded in the head and throat, and transported by helicopter to a hospital in Amiens.

He was reportedly operated on for several hours.

Operators of the Buffalo Circus said Loberot was recovering.

Buffalo circus added on its facebook page that the erring beast would not be killed.
