A giant lump of fat weighing as much as five sports cars has been cleared from a sewer in Chelsea, London.

The ten-tonne fatberg was so heavy it broke the sewer pipe it had stuck to, causing a bit of smelly surprise for local residents.

The giant lump was made-up of a mixture of fat, oil and grease which had cooled down and gone hard.

The fatty mess had then mixed with lots of wet-wipes to cause a nasty blockage.

The 40-metre-long fatberg cost Thames Water, who look after London's sewers, £400,000 to replace the damaged sewer.

Stephen Hunt works for Thames Water and said: "The amount of fat we've had to remove has been staggering.

"To have this much damage on a sewer almost a metre in diameter is mind-boggling," he said.
