A Brossard man, 27-year-old Nikolas Stefanatos, appeared in court in Longueuil Monday. He was charged with aggravated assault and remains in custody.
Longueuil police spokesperson Martin Simard called the attack a case of conjugal violence. He said police were called to the woman's apartment on Ste-Catherine Street at around 5 a.m. Sunday.
The woman, identified as Tanya St-Arnaud, 29, had burns to her face, arms and upper body, caused by a household product containing acid, Simard said.
"We know that the product is very dangerous for the skin if it's not diluted," Simard said. "The woman was taken to the hospital."
Simard said authorities do not fear for her life, but the woman is in a coma — likely medically-induced — so it will be some time before investigators are able to interview her for her version of the events.
Simard said St-Arnaud's assailant fled the apartment immediately after the attack but was picked up by police a few hours later.
Stefanatos is to appear in court for a bail hearing on Friday.
