Laval police have set up a command post at the Poly-Jeunesse high school in the Ste. Rose district as part of their effort to find a missing 14-year-old girl.
Athena Gervais was last seen at the school during the lunch hour on Monday. She didn't return to class that afternoon, and didn't return home that evening.
Police are hoping a student or a staff member may have seen her leaving school grounds that afternoon.
Police are concerned because she has no history of being a runaway.
The teen is known to use public transit and could be on foot.
She is white, French speaking, with brown hair and brown eyes.
She was last seen wearing her school uniform including dark blue pants, a red polo shirt and a hooded, dark blue, sweatshirt with a white "W" and the "WLKN" logo on the top.
Anyone with information is asked to call 9-1-1 or 450 662-INFO (4636).
