LAVAL, Que. -- The mother of one of three teenage girls who disappeared from a Montreal-area youth centre in the past few days is pleading for her safe return.

Josee Chaput says she fears her 16-year-old daughter Sarah Hauptman is at risk since going missing Saturday night.

Laval police are asking the public for help to find Hauptman and Mathilde Geoffroy Aube, 16.

A third girl, Kelly Martin Nolet, 14, was also reported missing but was found Wednesday evening in good health.

Major crimes Insp. Alain Meilleur said today all three were residents of the same group home and were said to have run away.

He says there is evidence the teens may have been targeted for sexual exploitation.
