Prosecutors have called for Laia Martin, 26, to be jailed for practising eight hours a day, five days a week at her home in Puigcerda, north-east Spain.

A neighbour lodged a complaint at the town hall claiming she suffered stress from the non-stop music.

Laia is a concert pianist who studied at the Liceu Conservatory in Barcelona.

But prosecutors accuse her of breaching noise pollution laws and of causing the neighbour psychological injuries. Her parents are also facing jail for allowing her to practise.

The pianist’s lawyer, Marc Molins Raich, said: “This is a good example of something the law should not get involved in.”
