Authorities say a 100-year-old man drove onto a sidewalk and hit 11 people, including nine children, across from an elementary school in South Los Angeles.

Los Angeles fire Capt. Jaime Moore says four of the children were in critical condition when firefighters arrived but they were stabilized and are now in serious condition at a hospital.

Moore says some of the victims were trapped under the powder blue Cadillac before witnesses helped pull them out.

Police identified the driver as 100-year-old Preston Carter. Investigators are interviewing him and say he is being cooperative.

A car sped onto a sidewalk and plowed into a group of parents and children outside a South Los Angeles elementary school Wednesday afternoon, and eight people were hurt, six of them seriously, authorities said.

At least some of the people injured outside Main Street Elementary were children, though it was not immediately clear how many, city fire spokesman Erik Scott said.

The crash occurred at 2:50 p.m., shortly after school had let out for the day, according to a statement from the Los Angeles Unified School District.

The school is about five miles southwest of downtown Los Angeles.

Scott said it was unclear whether the driver is among the injured, under arrest, or being sought.

Helicopter footage from NBC4 showed a child in a pink T-shirt being loaded into an ambulance and a Hello Kitty backpack lying in the street nearby. The footage showed a silver sedan on a sidewalk and a black car on the street next to it, both draped in police tape.
