A woman who waited a decade for detectives to charge the man accused of raping her is the second alleged victim pursuing a complaint about Queensland police losing forensic evidence.

Kelly*, who last year pressed for a fresh investigation that yielded charges within weeks, said a detective later told her that samples from her 2009 medical examination had been destroyed along with evidence in other cases.

Her account mirrors the case of Brisbane woman Eve*, who was told by detectives that potential sources of DNA in her 1995 gang rape complaint were destroyed with evidence in other cases.

The State Opposition called for the Crime and Corruption Commission to step in with a broader investigation after "another disturbing case of evidence going missing".

Kelly said her assault "in and of itself was devastating, of course, but I think the way that the police handled it has been the most devastating part of it".

"What I really don't understand is how 10 years later, we can be in a situation where the police consider it strong enough to prosecute, based on the evidence that they have, minus that forensic evidence which they have destroyed," she said.

Kelly said she felt "brushed off" by police when, a week before Christmas in 2009, she reported an alleged sexual assault by a man at her inner-Brisbane share house.

She told detectives that after the assault she vomited in disgust and locked herself in her bedroom.

An hour after interviewing the man, two male detectives came to her work at a busy cafe and handed back her underwear and leggings in a paper bag, saying they wouldn't be pursuing the case.

But last year Kelly, 35, now married with children and living interstate, pressed for a review, after a medical examiner suggested her chronic pain problems may be linked to sexual assault.

"In this era of more transparency, after the 'Me Too' whistleblowing, I decided that enough time and enough distance from my perspective has given me an opportunity to say no, being brushed off by the police was not okay," she said.

A detective wrote on the investigation file a day after she reported the incident in 2009, "investigations indicate highly doubtful offence occurred".

The file, obtained under Right To Information, also states the suspect denied the allegations.

Kelly said that's not what she was told.

"I was told that he admitted it, he was very sorry, he was very embarrassed — and that's as far as the police were going to take it," Kelly said.

Within months of her complaint last year, investigators charged a 41-year-old man with rape and sexual assault.

However, Kelly said a detective at Fortitude Valley police station told her that forensic evidence from her rape kit had been "destroyed in the process of a movement of storage and in that movement quite a bit of evidence had been destroyed".

"My response was, how is it possible to prosecute now 10 years later, with less evidence than what you had 10 years ago? How confident are you that this is going to be worthwhile putting myself through?"

Kelly said the investigation file note that a rape kit was not taken "as per the doctor's direction" was false.

"As a woman, it's not something that you're likely to forget. It's intrusive, and it's confronting, and it's an awful thing to have to experience," she said.

"Going through that process and having a rape kit taken, to then have that destroyed and then being told that it never existed at all … whether it's a gaffe or whether it was a conscious decision made by QPS, it's just not good enough."

The ABC has seen multiple emails in which Kelly has pressed internal police investigators about "destruction and mishandling of evidence".

They were written months before the ABC revealed the case of Eve.

"It's devastating to understand that I'm not alone but I guess there's some comfort in it," Kelly said.

"Who knows how widespread it is?

"Unless people are following these things up, they will never find out because the police aren't going to raise their hands and say, 'oh, by the way, we've lost your evidence'."

Queensland Police Service refused to answer specific questions about what happened to Kelly's rape kit "as this matter is currently before the courts".

But it referred to the disposal of "some paper records" in 2017 when police transferred "general correspondence and historical hardcopy investigation files between two archive locations".

"There were no physical exhibits stored, transferred or destroyed as part of this process," it said in a statement.

Investigation needed so it never happens again: Opposition

Opposition Leader Dep Frecklington said the emergence of another rape case involving missing evidence was "exactly why I wrote to the CCC".

"We need to ensure that the CCC investigates the entire situation, not just this case but any other cases," she said.

"These poor victims need to know that no more evidence has been lost or destroyed.

"If the system is broken and the CCC uncovers what has gone wrong here, we need to ensure that this never happens again."

Eve said it was "horrible to think that this has happened to someone else".

"Whether it was a mistake, or whether they've done it on purpose, I don't think that's something that anybody should ever accept."

Yesterday police arrested three men over Eve's alleged sexual assault — including two who will be extradited from interstate to face court.

Police Commissioner Ian Stewart last month told the ABC he saw the loss of Eve's evidence "as a mistake rather than a systemic issue".

"Obviously if there are any concerns about this case, the CCC will negotiate for a much broader look at our processes and programs that deal with our handling of exhibits," he said.

"I haven't seen a huge volume of complaints in this space."

Eve said she was "very, very disappointed and very, very angry" about this response.

"How would anyone else know unless they asked about it? I've been pushing the police for three years now," Eve said.

Queensland Women's Legal Service lawyer Julie Sarkozi said it was "very concerning that forensic evidence has been destroyed, misplaced, can't be found, isn't accounted for, in our police record systems".

She said the belated prosecution showed that "originally when the complaint was made, there was compelling evidence to charge the accused, but that that was not followed up correctly".

"I think the evidence that was very good 10 years ago has just been compromised by that timelapse."

The CCC was approached for comment.
