In an upscale California neighborhood outside Los Angeles, a grandfather was subjected to an unprovoked attack while pushing his 10-month-old grandchild in a stroller. The incident, captured on security footage, occurred as the grandfather was crossing an intersection in Calabasas. A man wearing a backward baseball cap approached him, and without warning, delivered a punch to the side of the grandfather's face, causing him and the stroller to fall to the ground. The assailant quickly fled the scene in a silver 2005 Honda Odyssey with Nevada license plates. Fortunately, witnesses reported that the baby and the victim sustained no serious injuries. As of Wednesday, the attacker remained at large.
