Toronto police say they have laid additional charges in a historic sexual assault investigation.

They allege a man acting as a caregiver sexually assaulted several young people between 2005 and 2013.

In 2017, police charged Kevin Marsh of the Toronto area with multiple counts of sexual assault and interference among other charges.

At that time, police alleged that Marsh had befriended two families at different times and then used his position of trust to sexually assault their children.
