US boy, 11, in gun heist

An 11-year-old boy joined four teens in a late-night gun shop heist that netted 15 firearms - then boarded a city bus for the trip home, Philadelphia police said.

All were arrested after a passerby alerted authorities to the burglary in suburban Collingdale.

The boy's mother told police she thought her son - who was caught in action by a security camera - was home in bed.

Police found the cache of weapons abandoned near the bus stop.
