An American sailor has suffered serious injuries after plunging eight floors from a  balcony of a hotel before landing into a swimming pool. Emergency services were called to the Parmelia Hotel in Perth at about 1am after a 22-year-old man jumped from the 10th floor and landed in the shallow end of the pool on the second level. Guests heard a disturbance between a man and a woman, who were visiting the city from the US naval ship USS Carl Vinson, at about 1am on Monday before the man leapt. Police say the pair were both heavily intoxicated when an argument escalated, which led the man to jump off the balcony where he landed in an estimate 1.3 metres of water.
