Multiple "fatbergs" are clogging up sewers beneath London's West End, it has been revealed.

Thames Water is closely monitoring four major blockages lurking under the streets of the capital's theatre district.

The masses of congealed fat, wet wipes, nappies and hardened cooking oil are in trunk sewers in Savoy Street, Lisle Street, Northumberland Avenue and Whitehall Place.

The capital's other major "fatberg" - described as a "monster", weighing 130 tonnes and more than twice the length of the Wembley football pitch - is under Whitechapel Road.
