A Spanish prosecutor's office says it may not seek the customary seven and a half year prison sentence for noise pollution for a pianist who practised at home.

The office for the north-eastern region of Catalonia said in a statement that it was studying a request for a partial pardon for 26-year-old Laia Martin, a professional musician, given that a "prison sentence could be considered overly stringent".

The office recommended prison earlier in the week after a neighbour claimed noise contamination from Martin's eight hour practice sessions had left her with psychological damage.

Regional newspaper La Vanguardia reports that Martin and her family were moving house today.
