At least eight people were stabbed, including two who were critically wounded, after a "large fight" broke out at an Oklahoma nightclub early Saturday, police said.
The incident occurred around 1:30 a.m. local time in Oklahoma City's Bricktown district, at the Pink Parrot Cantina, police said.
"Several police officers were posted outside the club as part of security protocols and saw the fight occurring with several injured people exiting the club, onto the sidewalk," the Oklahoma City Police Department said in a statement.

So far, eight people appear to have been stabbed in the fight, two of whom are in critical condition, police said Saturday. Six victims suffered minor injuries.
Police said it was unclear what caused the fight to break out. A weapon has not been recovered, an Oklahoma City police spokesperson told ABC News.
A suspect was taken into custody Saturday afternoon in connection with the incident, police said. Derick Walker, 19, was booked on one count of assault with a deadly weapon and two counts of assault with a dangerous weapon, police said.
"Investigation is ongoing and additional charges are likely," police said.
It is unclear if Walker has an attorney who can speak on his behalf.
A phone number listed for the Pink Parrot Cantina was not in service.

"I was about to pull into the garage. Right when I was about to turn in, I just see everybody started running across the street over here," Ben Dominguez told ABC Oklahoma City affiliate KOCO.
Dominguez said he saw a woman getting carried by two people and believes she may have been one of the stabbing victims.
"You just see people start scattering and running down that way, that way, across the street," he told the station.
