Gardai are liaising with the PSNI to investigate an alleged sexual assault on a young girl who became pregnant and miscarried after taking a cocktail of chemicals, apparently provided by an African witchdoctor.
The teenager, from west Dublin, is thought to have taken what has been described as "an abortion potion" given to her by her father.
He brought her to hospital in Newry after she suffered a bad reaction to the chemicals, apparently because he feared doctors in Dublin would call the gardai.
Gardai are now understood to be investigating allegations that the girl became pregnant after she was raped by her father.
The disturbing incident is believed to have taken place early last year and the gardai have been liaising with the PSNI and medical authorities in Northern Ireland to have the baby's preserved remains sent to the Republic for tests.
That lengthy process is reportedly near completion.
It is hoped that tests will detect the presence of chemicals used in the alleged witch doctor's concoction, and whether the foetus's DNA matches the girl's father.
Investigating officers were apparently tipped off by a relative of the girl who called Blanchardstown garda station early last year telling them the girl had suffered a painful reaction to the chemicals.
The relative told gardai that her father had brought her to Northern Ireland to avoid arrest.
When officers from the PSNI and gardai arrived at Daisy Hill Hospital in Newry where the girl's father had taken her, the teenager had already suffered the miscarriage.
The girl, whose father is an immigrant, is now understood to be in the care of the Republic's HSE. It's understood that her father has not been arrested.
Last night a garda spokesman said that their investigation into the alleged sexual assault dated back to "early 2012" and said it was "ongoing".
The spokesman said: "Gardai in Blanchardstown are investigating an alleged sexual assault on a female and are liaising with the appropriate agencies including the HSE, PSNI and our international police colleagues via Interpol."
The spokesman would not say whether officers were working with police in Africa nor would he specify a country.
An Interpol spokesman refused to provide any additional detail.
The HSE also refused to comment on the case.
