Ottawa police say a 16-year-old girl was arrested by police in Gatineau, Que., on Thursday evening and returned to Ottawa.
She is due in court this afternoon to face charges of human trafficking, procuring, forcible confinement, robbery, assault and uttering threats.
Two 15-year-old girls have also been charged in the case.
Police allege they lured three girls, between the ages of 13 and 17, to a home by posting messages on social media websites.
The victims were then allegedly forced to go to another location and perform sexual acts on men.
