Racehorse bucks jockey, escapes track and runs onto Kentucky highway

A 2-year-old filly got loose before a race at a Kentucky track and ran onto a highway alongside cars before being apprehended Saturday. 

The filly named Bold and Bossy got loose on her way to the starting gate at Ellis Park. The incident, which was live-streamed on YouTube, shows jockey Miguel Mena being thrown off and the filly running away. She then ran off the track and over a levee heading to U.S. 41. Bold and Bossy ran briefly onto Interstate 69  and Veterans Memorial Parkway, with a posse of trainers chasing her in their vehicles. Police and the sheriff's department also showed up.
