A Florida police vehicle knocked a motorcyclist off his bike during a high-speed chase Sunday along a freeway and was captured on video. In a pair of videos uploaded to social media, several Florida Highway Patrol vehicles are seen chasing someone on a motorcycle on Florida's Turnpike in Delray Beach, 55 miles north of Miami. The chase occurred next to a procession of bikers participating in the West Palm Beach Breast Cancer Awareness Ride Out, the Daily Mail reported.
