The Dundalk woman is being questioned by gardaí after she arrived back in Ireland.
Gardaí are continuing to question Lisa Smith over her links to the so-called Islamic State.
The Dundalk woman left Ireland over three years ago and was deported by Turkey over the weekend along with her two-year old daughter.
The 38-year old can be held for up to three days.
Garda Commissioner Drew Harris has said a de-radicalisation programme is not needed by the gardaí for suspected terrorists.

Mr. Power outlines what gardaí will be looking out for:
