The 210ft fatberg lurking in Sidmouth sewer

It has reached a length of 210ft (64m) to take the dubious accolade as the biggest fatberg ever found in the sewers of south-west England.

The congealed mass of fat and rubbish - built up when fat and cooking oil is poured down people's sinks - was discovered under the streets of Sidmouth.

South West Water is urging people not to "feed the fatberg".
