Quebec provincial police said that just before 7 p.m. ET Monday, a woman dressed as a nurse showed up at the Sainte-Marie pavillion of the Centre hospitalier régional de Trois-Rivières (CHRTR) and entered the maternity ward.
Police said the woman left the room a few minutes later, holding a baby wrapped in a blue blanket.
“She walked calmly down the hall, wearing a nurse's uniform. No one asked any questions about who she was,” a hospital employee told Radio-Canada.
Police issued an Amber Alert around 7 p.m., looking for a red Toyota Yaris hatchback with a "Bébé à bord" ("Baby on Board") sticker.
Police shared a photo on social networks of the woman police were seeking.
The child was found three hours later after four teenagers learned of the abduction through Facebook.
The teenagers say they went looking for the vehicle of the woman at the centre of the hunt, and found one that fit the description — then called police.
“We saw [the alert] on Facebook, and decided to go looking for red cars, and we saw the woman. We recognized her,” said Mélisane Bergeron.
Police say they arrested a 21-year-old woman at her home.
They found baby Victoria, and returned her to hospital.
The suspect is in hospital for a psychiatric evaluation, police say. She may appear in court later Tuesday.
The head of health services in the region says the hospital is co-operating with the police investigation and will also conduct its own internal review.
