The authorities had initially reported that the incident that occurred at noon in the tourist city in the western United States had left one dead and five injured.
The victims are “tourists and locals,” said Sheriff Joe Lombardo, in a brief statement to the media.

“The first incident occurred on the sidewalk and appears to have been unprovoked, there was no prior confrontation,” Las Vegas Metropolitan Police Department Detective James LaRochelle said.
“The suspect is a 30-year-old Hispanic man,” LaRochelle said. Authorities believe that he is not a resident of the community.
After the attack, the suspect would have left the scene running but was intercepted and taken into custody, the officer added, showing security camera video of the moment after the attack.
The weapon used was a long knife, he said.
