"I heard this unbelievable mayhem - a car accelerating and crashing and screaming," Klisser During said.
The photos appear to show a man in a brown shirt and jeans, alleged to be the driver of the car, fleeing immediately after the car crashed in the square.

A 26-year-old man is in custody. Authorities said the driver was a US citizen and former member of the US Navy. He has a criminal history, including driving while intoxicated.
Klisser During said she immediately thought it could have been another terror-related car attack.
"It was very much the feeling. Just confusion, not knowing, and then people just stunned," she said.
'"Sickening, nauseous, just shocked at such senseless killing.

"[Beforehand] people were chatting, relaxing, taking selfies, they were enjoying the plaza, enjoying the lights of Times Square, and then it was just chaos."
She said she walked to the aid of an injured woman who was being consoled by members of the public.
"There were no cops and the worst thing was there were no emergency services, no ambulances, nobody treating the people.
"Somebody was consoling a woman and I was saying 'they'll be here soon', but there was nothing to do for them."
