INDIANAPOLIS — Indianapolis police say a child and a school bus driver have been killed and two other people critically injured when the bus crashed into a bridge in the city’s east side this morning.

Police spokesman Sgt. Anthony Schneider says the bus carrying students from Lighthouse Charter School struck a bridge abutment about 7:45 a.m.

Schneider describes several other passengers as “the walking wounded.” It wasn’t immediately clear if two people reported critically injured in the crash were children.

Media reports said as many as 50 children ranging from ages 5 to 16 were on the bus.
