Police alerted over Kylie stalker

Kylie is to release a new single and album next month.

LONDON, England -- Pop star Kylie Minogue has called in police to investigate a series of threatening letters.

The 35-year-old singer is reported to have become concerned after receiving 700 letters at her home and office.

The letters, all from the west of England, started as ordinary fan mail but have been getting increasingly aggressive over the past year, according to The Sun newspaper.

One of the singer's management team went to Fulham police station in west London last week to report the harassment and ask for advice on how to deal with it.

A Metropolitan Police spokesman said: "An allegation of harassment was reported at Fulham police station on September 18 on behalf of a Chelsea woman.

"An investigation is ongoing at Fulham CID and at this stage there have been no arrests."

Former television soap star Minogue enjoys superstar status in Britain after a string of pop hits over the past decade including "Can't Get You Out Of My Head."

Earlier this year she launched her own range of underwear in London. Next month she is due to release a new single and album.

In April last year Kylie revealed she had been stalked by a fan for five years, and said he had even managed to find out where she went shopping.

"I'm sure he means no harm," she added.
