LAS VEGAS — A woman intentionally swerved her car onto a busy sidewalk two or three times Sunday and mowed down people outside a Las Vegas casino, killing one person and injuring at least 30 others, police said.

The vehicle was in the northbound lanes of Las Vegas Boulevard near Bellagio Way when it drove up onto the sidewalk about 6:30 p.m. in front of the Paris Hotel & Casino and struck pedestrians, Las Vegas Metropolitan Police Department Lt. Peter Boffelli said. The person killed was an adult, he said.

Police believe this was an intentional act by a woman in her 20s who “went up and off these streets, two or possibly three times,” Lt. Dan McGrath said. Police did not give a possible motive.

The woman is being interviewed and is having her blood drawn, police said. She is being held in the Clark County jail with charges pending.

The crash in front of the Paris and Planet Hollywood hotels occurred on a busy stretch of the Las Vegas Strip across from the dancing water fountains of the Bellagio hotel-casino. The Miss Universe pageant was being held nearby at the Planet Hollywood Las Vegas Resort & Casino at the time of the crash.

Police are reviewing video from casino-hotel surveillance cameras, Capt. Brett Zimmerman said. “We know this was not an act of terrorism,” he said. “We will comb through that footage to get a detailed idea of what occurred. “

After the crash, the vehicle continued to head east on Flamingo Road before it was found at a hotel, McGrath said. The driver was arrested at the hotel, police said. A 3-year-old child was in the vehicle with her but was not hurt, Zimmerman said.
