NEWARK, Del. — Delaware State Police have arrested a caregiver they say hit a 13-year-old autistic resident of a group home where she works.

The agency said in a news release that the caregiver worked at the Manor Group Home, which is owned by the Christina School District. Police say the caregiver was seen repeatedly hitting the boy, who is autistic and doesn’t speak. Troopers say another staff member intervened and stopped the assault.

Authorities say a school nurse wrote on an injury report that she saw redness and bruising on victim’s right upper arm and scratches on the back of his neck.

Officials say warrants were obtained and on Tuesday, 53-year-old Harrietta Kanda of New Castle was arrested. She is charged with felony child abuse and endangering the welfare of a child.
