SAN FRANCISCO >> Passengers aboard a SuperShuttle van bound for the San Francisco airport were left standing by the side of a road after one of their fellow riders ousted them and stole the vehicle.

The San Francisco Chronicle says the shuttle had picked up 3 travelers at hotels in downtown San Francisco on Sunday when a fourth rider boarded the van.

When the shuttle stopped to pick up a fifth person and the driver got out to help load luggage, the suspect took the wheel and drove off.

After a few blocks, the man stopped the van and let the passengers out with their suitcases. The four stranded riders then called a taxi and split the fare to the airport.

Police say the van was found later Sunday in Alameda County, but the driver remains at large.
