A security guard nearly lost his life while battling 25ft long python.

The 37-year-old security officer was at work when he saw the snake in the premise.

In an attempt to contain the dangerous reptile, Robert Nababan tried to stuff the gigantic python into a bag (sic), a decision that proved to be fatal.

The python nearly severed his arm off his body in defense as they fought on for quite a while. It took the villagers intervention to save Robert who is now fighting for dear life at a local hospital.

The villagers killed the snake with a log and then put it up on display while they made preparations to turn it into a feast for the village of Sumatra Island in Indonesia.
