Gardaí are investigating the alleged false imprisonment and assault of a woman in her 40s in County Louth last Wednesday.
The victim is currently receiving medical treatment for an eye injury at Dublin's Mater Hospital.
This incident occurred at a house in Muirhevnamore in Dundalk.
Gardaí have since carried out searches at two houses in the Dundalk area and seized a car they believed was used as part of the attack.
A man in his 30s who is in custody in relation to a separate matter is being questioned in relation to the incident and is currently detained at Dundalk Garda Station.
