The free bikes Facebook provides for its employees are being dumped in surrounding neighborhoods.
This is causing issues, with reports of local kids being stopped by police when they try to ride the abandoned bikes.
It seems that in some cases Facebook employees are riding the bikes into town then leaving them, and in other cases, they're being stolen from Facebook's offices.
The baby-blue bikes, which are supposed to be used to get around Facebook's sprawling Menlo Park, California campus, are turning up in nearby Bay Area neighborhoods like East Palo Alto after being dumped.
"Bikes are often abandoned by restaurants, bus stops, the train, and dumped in the San Francisquito creek or the baylands.
The incidents highlight the headaches tech giants like Facebook can cause for their neighbors in the Bay Area, who are already struggling with soaring house prices and gentrification fueled by the tech sector.
