A Connecticut nanny accused of beating and burning a 3-year-old girl on a stove has pleaded not guilty to charges of assault, risk of injury to a child, and criminal mischief.

Lidia Quilligana was arrested on March 20 after police say she was caught on a hidden camera force-feeding the child, physically abusing her, and pressing her hands and leg to a stove burner.

Police say the Danbury nanny told the victim's mother the girl was injured when she pulled a chair up to the stove, touched the burner and then fell and hit her head on a stove knob.

The 31-year-old Quilligana, originally from Ecuador, was the full-time baby sitter for the girl and her two younger siblings.

She is due back in court May 27.
