A Quebec woman is in an induced coma and has her face covered in bandages after having corrosive acid thrown in her face.
More than 4,000 messages of support on Facebook have rolled in for Tanya St-Arnauld.
The 29-year-old Ms. St-Arnauld remains in hospital with burns to her body.
Police in Longueuil, south of Montreal, arrested Nikolas Stefanatos shortly after the Sunday morning attack.
Police say Mr. Stefanatos is Ms. St-Arnauld's boyfriend.
He appeared in court Monday and was charged with aggravated assault.
A police spokesman says investigators have not yet been able to question Ms. St-Arnauld because of her condition.
Mr. Stefanatos is to appear in court for a bail hearing on Friday.
