Joanna O’Driscoll (43) has also publicly apologised for her actions in a post on social media saying “My apologies don’t mean anything but I truly am sorry.”
Ms O’Driscoll, of Clusker Park, Navan, Co Meath appeared before Judge Ciaran Liddy at Trim District Court on Thursday morning.
She entered a guilty plea to using or engaging in threatening, abusive or insulting words or behaviour with intent to provoke a break of the peace or being reckless as to whether a breach of the peace might have been occasioned on March 21 at St Mary’s Church, Trimgate Street, Navan, Co Meath.
That offence is contrary to Section 6 of the Criminal Justice (Public Order) Act, 1994 as amended by Section 22 of the Intoxicating Liquor Act, 2008.
The court presenter gave evidence of arrest, charge and caution by way of schedule.
Represented by solicitor Maurice Regan, Ms O’Driscoll entered the guilty plea. She has eight previous convictions, the court heard.
Through her solicitor she also apologised to the court and told the court she is scheduled to attend Cuain Mhuire next week.
Judge Liddy convicted and fined her €100 and gave her six months to pay the fine.
The incident happened as hundreds of six class children from four schools around Navan, Co Meath as well as their parents and sponsors, packed St Mary’s Church on Saturday, March 21 when Ms O’Driscoll made her way to the altar and told the crowd she had something to say.
After she said she had a bomb, teachers and a priest calmly escorted her off the altar and outside the church.
Ms O’Driscoll was arrested by gardai at the scene and charged with Section 6 and appeared before Trim District Court on Thursday, April 9.
In her public apology on social media, Ms O’Driscoll wrote: “I know this has taken me a while. As everyone knows it was me in the church that day. I can’t explain or I don’t have any excuses for my actions.
“My apologies don’t mean anything but I truly am sorry. I don’t know who that person was or remember. I got lost somewhere along the line. I lost myself. I’ve shamed my family and partner and his family in the process of my actions. For all those parents and kids in that church that day I am so, so sorry," Ms O'Driscoll wrote.
“My mental health and addiction has taken over and I know it’s no excuse. For all the people who know me knows that’s not me.
“As for the ones who judged and made videos and commented bad, all I can say is I pray to God it never lands on your door.
“My journey to recover and peace is starting. No one knows my story or my mental health or addiction so please always keep in mind or think before judging.
“And once again I’m so sorry to all the parents and kids, especially my nephew and family and also to the parish and bishop.”
