A man accused of assaulting a three-year-old boy in Weyburn made his first court appearance Tuesday.

Andrew Harper was charged with aggravated assault after the boy was seriously injured at a home in Weyburn on Saturday.

Police say the 32-year-old is known to the victim, but at this point, the exact relationship isn't clear.

At last word, the boy was still in critical condition after undergoing emergency surgery at a Regina hospital.
