Footage shows 'monster' fatberg in an east London sewer

A 250-metre long fatberg weighing 130 tonnes has been found blocking a sewer in east London.

A section of the mass of congealed fat, wet wipes, nappies, oil and condoms was filmed by Thames Water engineers working to unblock the sewer.

The company said it would take three weeks to remove the blockage.
