Complaints called in by neighbours led to a human trafficking arrest on the Mountain Wednesday evening, police say.

Around 7 p.m., officers went to a Mountain home after getting noise complaints and reports of “ongoing trespassing,” police say.

Once inside, officers spoke with a 50-year-old man and a 16-year-old girl. After looking around the residence and speaking with them both, the officers became suspicious that the teen was involved in the sex trade, police say.

The police human trafficking unit was called in, and investigators determined she was, in fact, a human trafficking victim.

While they were interviewing her, police also found an 18-year-old man hiding out in a bedroom in the back of the home.

The 18-year-old was arrested and charged with trafficking a person under the age of 18, living on the avails of prostitution, and a host of other sex trade-related offences.

The teen girl was taken from the home and places in a safe location, police say. “Resources to assist the female have been provided,” a police news release reads.
