A Los Angeles County Sheriff's deputy vehicle crashed into another car and was sent hurtling toward a pedestrian sidewalk near downtown LA.

The second car involved in the collision then hit a third car, 'causing injury to two additional adult pedestrians in the crosswalk,' a Los Angeles Police Department spokesperson said. 

Just after 7:20pm, the accident took place near the intersection of Indiana Street and Whittier Boulevard, according to the LAPD.

'When I got there I saw a little boy with a white blanket over him. Another one across, I'm not sure if he was conscious or not, but it didn't look like he was.'
