A man from Assiniboia, Sask., who was already in custody charged with sex crimes against children, is now facing 60 more charges after further investigation into alleged sexual assaults of minors over an 18-year time span, RCMP say.

Police arrested Richard John Dyke, now 47, whose home was a licensed daycare, in November 2023.

He was charged with 13 total sex offences after police said investigators had determined three boys younger than 12 were sexually assaulted in the mid-2010s.

In a news conference Tuesday, RCMP said they have identified 29 additional victims, all youth between the ages of 18 months and 17 years of age when the offences occurred, with the majority being male.

The alleged offences date from as far back as 2005 to November 2023.
