During her heyday in the 1980s, Anita Mui performed for 28 consecutive nights to sold-out houses, breaking the Hong Kong record at the time. (AFP pic)HONG KONG: The ashes of late pop superstar Anita Mui, once dubbed the "Madonna of Asia", have gone missing from a monastery in Hong Kong, police said Tuesday.

The diva of Cantopop - a popular music genre sung in the Cantonese language - died from cervical cancer aged 40 in 2003 after selling millions of records.

Mui's family went to the police in July after a fan spotted that the urn was no longer in its place, but without going public.

However, on Saturday they issued a statement saying that the lack of progress in the police investigation was causing them "tremendous distress and emotional anguish".
