(AP) — A 10-year-old girl remains in critical condition after she was struck by a school bus in her suburban Salt Lake City neighborhood.

South Jordan Police Sgt. Sam Winkler said the girl was “still extremely critical” Thursday afternoon, but he did not release further details.

He says the girl had just gotten off her bus Wednesday afternoon and was crossing the street when she was struck by a second bus.

She was taken to a nearby hospital then flown to Primary Children’s Hospital in Salt Lake City, where she underwent surgery and remains in critical condition with head injuries.

Winkler says the second bus driver didn’t see the girl. The accident remains under investigation.

Police earlier reported the girl is 8 years old but later confirmed she is 10.
