It is believed an acid attack on a 32-year-old Chinese national in Dublin on Friday may have been orchestrated by another woman.
It is understood the attack happened in a walkway between Merrion Woods and Seamount Apartments.
A man grabbed her from behind, pushed her to the ground, and poured what appeared to be acid in her face.
Gardai are appealing for information about a heavy set man seen wearing dark clothes in Blackrock at the time of the assault.
The woman's face and hands were seriously burned when a caustic substance was thrown at her.
