MONTREAL -- Whenever Tanya St-Arnauld closes her eyes, she relives the evening five months ago when she says ex-boyfriend doused her with acid in a fit of jealousy.

St-Arnauld told QMI Agency's sister French news channel, LCN, that the Aug. 25 attack is never far from her mind.

"Every detail, every sound, even the acid smell ... that's what I see all day," the 29-year-old hairdresser said.

Nikolas Stefanatos is charged with assault following the attack in Longueuil, just outside Montreal.
