LAS VEGAS -- A driver plowed into a sidewalk several times at the Las Vegas Strip, injuring nearly 40 pedestrians in what authorities described as an "intentional" act.
At least one person was killed and 37 others injured near the Paris Las Vegas hotel Sunday night, authorities said.
The driver is in custody, and undergoing tests for alcohol and controlled substances. A 3-year-old child in the car with her was unharmed.
"This was not an act of terrorism," Deputy Police Chief Brett Zimmerman said.
'She just kept mowing people down'
Antonio Nassar, who was at the Strip, said people scrambled to stop her as she careened into the sidewalk.
"The car rolled right in front of me. By the time I looked over to the right, all you could see was [her] driving away and people were bouncing off the front of the car, you can hear it," Nassar told CNN affiliate KLAS.
"She rode the sidewalk, she came to a stop at the Paris intersection, people are punching into the window ... she accelerated again and just kept mowing people down."
Rows of ambulances and police cars gathered at the scene, their lights flickering.
Police rule out terrorism
Witnesses described chaotic scenes as crowds fled.
"Everyone was running ... and as I was running, I saw a car up on the sidewalk coming toward us," a witness told the affiliate. "I saw a lady, she didn't seem like she wanted to stop the car, she had both hands on her wheel and she was looking straight forward."
Others tried to stop the driver and drag the toddler out, she said.
"I saw men running after her, yelling, 'stop, stop!' As she was passing, we saw people running after her. Everyone was so frantic and just running around."
Traffic snaked down the streets as cars were diverted near the Paris Las Vegas hotel.
As the night wore on, the streets emptied.
