Huge 'fatberg' removed from sewer

A 'fatberg' the size of a double-decker bus has been removed from a sewer in London.

The 15-tonne mass of food fat mixed with wet wipes was removed from underground pipes in Kingston in Surrey.

It was found when residents complained they couldn't flush their toilets.

Thames Water, who run the sewers, believe that if it hadn't been removed, it could have led to sewage flooding homes, streets and businesses.
