From the Associated Press:

LOS ANGELES — Authorities say a 60-year-old man has been arrested on suspicion of kidnapping a 6-year-old girl on a Los Angeles bus.
Los Angeles County Sheriff’s Capt. Mike Parker says a homeless woman reported her daughter missing early Sunday. The woman told authorities she fell asleep on a bus near downtown and when she awoke the girl was gone.
About two hours later the driver of another bus reported seeing the girl board his vehicle accompanied by a male suspect.
Deputies responded and arrested the man, identified as John Thomas.
The girl was unhurt and taken into protective custody.
