This is the terrifying moment rescue workers grappled with a giant king cobra that was caught hiding under a kitchen sink.<br /><br />The 17ft long snake had slithered inside a washing machine then darted out under the sink when it was disturbed in Krabi, southern Thailand yesterday (February 6).<br /><br />The house owner, Khun Gommaton, heard the reptile clattering around knocking over empty bottles of washing powder. <br /><br />He initially thought it was a mouse and followed the sound - shrieking when he noticed the cobra's head.<br /><br />Gommaton said: ''The clattering was getting louder and louder. I really thought it was a mouse, so I intended to take it out myself. But I was totally wrong.''<br /><br />Krabi rescue officers responded to the house owner’s call and took more than 15 minutes trying to capture the hiding serpent.<br /><br />They are seen in the footage visibly struggling and shaking as they grapple with the powerful snake.<br /><br />The officer said that it is one of the biggest venomous snakes he had ever caught. He added, ''It's very huge and heavy. I think it weighs about 20 kilograms (45 pounds).<br /><br />''It might have been looking for food around here. We are going to take him back to the natural habitat, where there are no houses and people around.''
