The Irish Independent is reporting that a 16-year-old schoolgirl was left "red-faced" after she received pro-life material in the post.
The letter arrived to the girl's Dublin home and requested finances to fund a campaign by a pro-life group.
The girl's mother told the publication that the letter was six pages and contained "propaganda" material about the Eighth Amendment.
The letter states that if it is repealed: "abortion 'clinics' will pop up all over Ireland, in Dublin... Dundalk... Waterford... Cork... Limerick... and Galway. They will be an ugly blight on our towns and cities, a constant reminder of the normalisation of killing."
The girl's mother said that she was "horrified" and that her daughter was left "mortified" and "shocked" by the letter.
"It was a six-page letter with a standing order mandate included and a pre-paid return envelope. [The letter] goes into some extreme details."
One finance option included in the letter said that if you could send "€50 right now", the campaigners asked you to make it "€75 instead."
"Think of what you can give up to send €75 instead of €50, and ask yourself is that sacrifice not worth it."
The group's Director said that it was not their policy or practice to contact under-age students for money of any campaign and that "this was an unfortunate and exceptional error" that "should not happen again"
