Nikolas Stefanatos is charged with aggravated assault in relation to an incident on Aug. 26 in which his girlfriend, Tanya St-Arnauld, had a corrosive fluid — possibly a drain or concrete cleaning agent — thrown on her during a domestic dispute.

St-Arnauld suffered burns to a fifth of her body and had to placed in a medically induced coma for four days.

Provincial court Judge Claude Provost said Tuesday at the Longueuil courthouse that the acts Stefanatos is accused of constitute pure "barbarism" and that he would present a risk to society if released on bail.

Stefanatos's lawyer had asked for her client to be sent to a detox centre because he has multiple substance addictions. The judge didn't rule out that possibility but said there would have to be strict procedures in place.

St-Arnauld's mother, Linda St-Arnauld, welcomed the judge's ruling.
