Police in London are not treating the death of Dolores O'Riordan as suspicious.
The Metropolitan police completed their preliminary investigation and the case will now be sent to the local coroner.
The 46-year-old singer from Kilmallock in Limerick was found dead at a hotel in London yesterday morning.
Tributes have also poured in from the world of music for the mother-of-three, while a number of fans braved the adverse weather conditions to sign a book of condolences opened at Limerick City and County Council.
One of the first to sign the book was the principal of the singer’s old school, Laurel Hill Colaiste in Limerick.
Aedin Ni Bhriain said the school is very proud of everything O’Riordan achieved.
She said she never forgot her roots and even asked the school choir to sing at her wedding.
“We wanted to express our sympathy to her family because it is such a loss for them and also to show our deep love for everything she did and out admiration for everything she achieved,” she told the Press Association.
“We are very proud of her as a past pupil and also because she was a Limerick woman who never forgot she was a Limerick woman. She kept the links with Limerick. We are so proud of everything she achieved.”
The school community of Laurel Hill Coláiste FCJ would like to express its heartfelt sympathy to the family of Dolores O Riordan on their sad loss.
