Three people were stabbed and a man was arrested Tuesday night after an argument outside a downtown restaurant.
Las Vegas police said the stabbings happened about 9:45 p.m. outside Hennessey's Tavern at 425 Fremont St.
A group was attending a work function when an argument broke out, police said.
Ariel Palomares, 31, fled the scene of the fight but was later arrested.
The men who were stabbed were identified in the police report as Edward "Mike" Okada, 34; Edmundo Delgado, 27; and Justin Claudat, 32.
Okada was listed in critical condition at University Medical Center. Delgado and Claudat were treated and released, the report said.
"I believe alcohol may have been a factor," said Lt. Jeffrey Whitehead. "Everyone involved was intoxicated."
According to the report, Okada, Delgado and Claudat were part of a group of co-workers who were at Insert Coins, 512 Fremont St., before walking in front of Hennessey's.
Outside, they saw Palomares stumbling and bumping into people.
The report said Palomares first struck Okada, which began a fight between the men and one of Palomares' friends, Frederick "Cory" Millett, 21.
Okada was stabbed once in the upper left chest, Claudat was stabbed on his left side, and Delgado was stabbed once on his upper torso, the report said.
Palomares fled south on Las Vegas Boulevard. The report said officers found a knife in a garbage can at Carson Avenue and Las Vegas Boulevard.
Police caught up with Palomares at Third Street and Lewis Avenue after he called Millett.
Palomares told investigators he drank an entire bottle of vodka before going to Insert Coins. He said he didn't remember anything that happened after he left the business.
He confirmed to police that the knife they found matched a knife he carried.
Palomares was booked at the Clark County jail Wednesday morning on three counts of battery with a deadly weapon.
