Used condoms sent to ex-pupils of Melbourne school

Australian police are investigating after at least 65 women received used condoms in the post.

The letters, which also contained handwritten messages, were sent to addresses in south-eastern and eastern Melbourne.

Police believe the victims are linked and part of a targeted attack.

All of the women who have come forward attended the city's Kilbreda College private girls' school in 1999.

Most of the victims received multiple letters, all with used condoms enclosed, police said.

Investigators were carrying out DNA and handwriting analysis to track down the perpetrator, said Detective Acting Senior Sergeant Grant Lewis.

The women's addresses were obtained from a yearbook they put together as pupils 24 years ago, he said.

Some letters were handwritten, some typed, but all contained "suggestive and threatening... sexualised " messages, he said.

"Our message to the offender would be 'you need to stop this' and 'we will find you'".

"We don't know what the connection to the school is. It might be an ex-student, an employee... it could be someone who found this yearbook in the rubbish and they're playing a game".

Many of the letters were sent to the women's old home addresses and were opened by their parents, who were traumatised and distressed by the ordeal.

One victim, Bree, told reporters of how her mother called to ask whether she should open an "odd letter" she had received. She asked that her full name be withheld.

"Her reaction was quite shocked and upset. She was really grossed out and her and dad were worried thinking someone was targeting me".

Bree said the similar complaints snowballed and she soon formed a Facebook Messenger group among fellow Kilbreda College alumna.

"It seemed to be every day or two days more and more girls would say 'I've got one'."

"It's beyond a joke now. We just want it to stop. One of the girls has received four letters and she's just over it."

"We've got no idea who it could be. No one can seem to find a connection. We can't think of anybody who has a grudge against us."

Police have urged anyone with information to come forward.

Kilbreda College, an independent Catholic school for girls, was founded by the Brigidine Sisters in 1904 and has some 900 pupils enrolled.

The college is assisting with the investigation, police said.

Principal Nicole Mangelsdorf told Melbourne's Herald Sun newspaper that the school had written to former pupils encouraging any other victims to come forward to the police.

"We have no reason to believe this matter is related to any recent data breach at the college", she said.
