Footage shows the moment a BMW car was swept away in the River Thames, sinking slowly as it went, on Wednesday.<br /><br />The vehicle had reportedly been parked on a slipway leading to the river at Putney Embankment when it was pulled in entirely by the tide.<br /><br />The filmer, 18-year-old student Ted Stones, wrote online: I was walking down the bank a few hundred metres from the bridge and saw a couple of people and police van. When I got there the water was nearly up to the top of the wheel arches.<br /><br />"Then after about 5 mins the car slowly became more buoyant before suddenly being lifted enough and started floating away. It was such an odd experience. You hear of cars getting trapped in a bit of water after high tide but never being swept completely away!<br /><br />"The police had literally no idea what to do and stood there pretty much helpless. They were constantly radio-ing to other polcie/pla but were obviously unable to do much. By the time the PLA got there the trunk was pretty much fully submerged and it did eventually completely sink."
