This is the terrifying moment a 10ft long python was caught hiding in the toilet - after biting a man's penis. <br /><br />Terdsak Kaewpangpan, 45, went to the loo but while he was sitting on the seat, the python leapt up and plunged its fangs into Terdsak's genitals.<br /><br />Terdsak howled in pain as colleagues rushed in to find him wrestling with the reptile.<br /><br />He ripped off the snake - which had clamped its mouth around its manhood - and dashed outside into a car with blood pouring from his groin. <br /><br />Terdsak had 15 stitches in his penis and rescuers arrived to grapple with the python, which had reportedly been living in the pipework for several weeks. <br /><br />The office worker said: ''I was about stand up from the toilet. Then I felt a bite in my penis. I immediately knew it was a snake. I stood up and grabbed the python’s head then pulled it off me. There was blood everywhere. I should have been more careful. I saw a snake in another toilet in the house two months ago so I was using this one instead. But I didn't realise the toilets could be connected.''
