"A pack of young bicyclists attacked a BMW in broad daylight in Manhattan, terrorizing the man and woman inside in a terrifying ambush caught on video."

"Several assailants surrounded the luxury ride at Fifth Avenue and 21st Street around 4:30 p.m. Tuesday, with some pounding the vehicle with their fists and feet, and another smashing a bike down on top of it...  One attacker got a running start, vaulted up on the hood of the BMW and jumped on top of the windshield, causing it to partly cave in... The same group similarly attacked a cab a short time later...."
