Authorities say seven people were critically injured in a hit-and-run crash involving two cars in Hollywood.

Los Angeles Fire Department spokeswoman Margaret Stewart says the victims include a 1-month-old boy, a 2-year-old boy, a 16-year-old girl and four adults.

The crash triggered a police search for a suspect who was seen running from the scene of Saturday night's crash at the intersection of Santa Monica Boulevard and Orange Drive.

Police Sgt. Clifton Frazier said the suspect was the driver of the car believed to have caused the crash.
