Muchen Hsieh, 19, traveled from Boston by Megabus Tuesday to spend the Christmas holidays in Philadelphia, The Boston Globe reported. A half hour after her arrival, she realized she had forgotten to retrieve her instrument from the overhead luggage rack.
Megabus employees in Camden, N.J., searched the bus, Bryony Chamberlain, a company spokeswoman, said. Chamberlain said employees queried police in Philadelphia after they found a violin.
"We knew we found a violin, and we knew a violin was missing, but that doesn't necessarily mean they are related," she said.
Philadelphia police gave the instrument to Hsieh.
A foundation in Taiwan provided the instrument, made in 1835 in Naples by Vincenzo Jorio, KYW-TV, Philadelphia, reported.
Hsieh is not the first musician to lose an instrument while traveling. Internationally famed cellist Yo Yo Ma once got his cello back after leaving it in the trunk of a New York taxi.
