THE HSE has complained to the Data Protection Commissioner about a breach of confidence in the case of the young teenager who was found in a distressed state outside the GPO recently.
Confidential information about the young teenager was accidentally sent to a business that has a similar domain name to the HSE.
The email - which was originally sent by the Psychiatric Nurses Association (PNA) and is believed to have been subsequently forwarded on by someone else - was meant for members of the trade union within the HSE.
The email sought their help in identifying the girl and contained private information about her, as well as a photograph taken in a Dublin hospital.
A HSE spokesperson said: "As confirmed by the Data Protection Commissioner the responsibility of data protection is on the controller and sender of the information, in this case the sender of the information was not the HSE."
"Should any action be required on the part of the HSE by the DPC the HSE will co-operate fully."
Another HSE spokesperson said: "We would always notify the Data Protection Commissioner in relation to a breach."
The PNA is now investigating the accidental email slip-up.
Seamus Murphy, Deputy General Secretary of the PNA told independent.ie: "We're absolutely satisfied from our head office here that it went out to the right people. We checked our own list and we're a 1000 per cent satisfied."
"We can guarantee that noone was sent it that shouldn't have been sent it."
The PNA is currently questioning its members as to whether they forwarded it on to non-PNA members.
Meanwhile, gardai are considering seeking a court order so they can publish a photograph of the teenager - who is a suspected sex trafficking victim - in a bid to identify her.
The girl, believed to be aged around 14 and from Eastern Europe, was found abandoned outside the GPO on O'Connell Street 11 days ago.
Gardai say the girl is deeply traumatised and fear she is the victim of sex traffickers and that she suffered sexual abuse over a prolonged period.
Denise Charlton, CEO of Immigration Council revealed on RTE's Morning Ireland this morning that the sex trafficking industry, led by "mafia type gangs", in Europe is worth €25 billion.
"We know there are 1,000 women and girls for sale," she said, adding that many of these enter the trade while underage.
She said prostitution and sex trafficking are prevalent online and "you can order a young girl to anywhere at the minute".
She added that the Immigration Council did not know for sure yet if the lost teenager had been trafficked, but she urged Irish men to think twice before buying sex.
