WATCH: Security Camera Captured Shocking Crash Of Ukrainian Millionaire's Daughter

An oligarch's daughter who killed five people and injured a dozen more in a horror car incident had allegedly been racing another driver.

Alyona Zaitseva, a 20-year-old millionaire's daughter "jumped a red light and rammed into a crowd" at a pedestrian crossing, say police.

A new video suggests she could have been racing another car moments before colliding with a vehicle and ramming into helpless pedestrians waiting at a crossing in Kharkiv, Ukraine.

The CCTV shows two cars side by side travelling down a busy road with lots of traffic.
