While flying from Idaho to Florida, a teen with an Asperger’s-like condition found his plane unexpectedly diverted to an unfamiliar city and wound up wandering the streets all alone.

Joshua Arvin, 15, was on his way home from his boarding school when his flight to Fort Lauderdale, Fla. instead stopped in Tampa. Rather than follow the rest of the passengers to a bus for the remainder of the journey, the teen attempted to make his own way.

Arvin’s mother, Tracy, frantically called the airline and airport police with no luck tracking down her son. She later learned that the teen tried to charter a bus before taking a cab to a local bus station. He was ultimately found on a downtown street corner after 11 p.m by a good Samaritan who called police.

The airline — US Airways — says it does not accept responsibility for unaccompanied minors on connecting flights, reports WTSP, the Tampa CBS affiliate.
