A mental health counsellor has been accused of sexually assaulting a 14-year-old client over a period of a year.

Peel police said the victim, a girl from Mississauga, contacted them recently, reporting several sex-related incidents over a period of a year beginning in late 2016.

Peel's special victims unit investigated the allegations.

On Tuesday, Sept. 18, they arrested and charged Dennington Duncan, 51, of Brampton. He has been charged with sexual assault, sexual interference and invitation to sexual touching.
