ORILLIA, Ont. -- Provincial police say an infant remains in hospital following a serious assault, allegedly by the child's father.

Investigators say they were notified on Dec. 29 by Simcoe Muskoka Family Connexions -- an Orillia, Ont., child welfare agency -- about a serious incident involving an infant.

They say a 20-year-old Orillia man has been charged with aggravated assault and failing to provide the necessaries of life.

He is scheduled to appear in court on Jan. 31.
