LAUGHLIN, Nevada (CNN) --Rival motorcycle gangs clashed in a southern Nevada casino early Saturday, leaving three men dead, at least 13 other people wounded and -- for a few hours -- an entire town on lockdown, according to law enforcement and emergency officials in Nevada and nearby Arizona.

Police, who characterized the melee at Harrah's Laughlin Casino as the worst shooting incident in the history of Nevada casinos, were questioning more than 200 people, 'trying to separate the witnesses from the victims,' said Lt. Vincent Cannito of the Las Vegas Metropolitan Police Department, which provides law enforcement in Clark County, where Laughlin is located.

One person has been arrested, Cannito said. 'With regards to the other people who have been detained, their status hasn't been determined yet,' he added.

In addition to the 'large number of people in custody, we have numerous weapons,' he said -- 'knives, guns and tools.' Citing the 'sensitivity of the investigation,' Cannito would not specify how many people are in custody or what charges they are facing.

The incident happened just after 2 a.m. Saturday (5 a.m. EDT). Cannito said a member of the Mongols motorcycle gang wandered into a group of their rivals, the Hells Angels, and a fight broke out which escalated into gunfire.

After the incident, Nevada officials sealed off Laughlin while they searched for anyone connected with the brawl, said Larry Tunforss, a fire department spokesman in Bullhead City, Arizona, across the Colorado River from Laughlin.

The restrictions were lifted a few hours later.

Tunforss said 10 wounded men were taken to Western Arizona Regional Medical Center in Bullhead City and another was airlifted to Las Vegas.

Tunforss said the Arizona facility received seven gunshot victims, one man with skull trauma, a stabbing victim and a man with chest pains.

Four of the 10 men taken to Bullhead City were later flown to Las Vegas, 84 miles away.

None of the dead were casino employees, he said.

By 5 p.m. (8 p.m. EDT), the hotel towers, three restaurants, and one of the casinos had reopened, said Laura de la Cruz, director of marketing for the hotel.

The 1,700-room hotel was 100 percent booked, she said. Asked whether any guests had sought refunds in the wake of the violence, she said, 'We're currently working on that process right now.'

Laughlin, about 80 miles southeast of Las Vegas, has a year-round population of about 8,000. This weekend is the 20th annual 'River Run,' an event which annually draws 50,000 to 80,000 motorcycle enthusiasts.

Cannito said the event usually goes off 'without a hitch,' but 'outlaw' gang members provoked violence this year.

'It's the 1 percent fringe society members that don't want to be part of society,' he said.

Because of the motorcycle event, police already had a heavy presence in the town and responded within two minutes of the shootings, Cannito said.

He said officers were prepared to put a stop to the motorcycle event, if more violence appears likely. 'If there is a legitimate need to close this event down completely, that will be done.'

Saturday evening, Cannito announced that police had shut down a bridge leading into Laughlin from Bullhead City as well as a road from the Davis Dam.

'Those are the ones we've verified as possible threats,' Cannito said. 'Those are the ones that we've closed down.'

In amateur video taken of the melee, a police officer is seen wrestling with a suspect when his gun appears to go off. 'It appears to be an accidental discharge,' Cannito said.

There was also another shooting in which an officer was involved, Cannito said. 'That was not an accidental discharge. That officer was confronted with gunfire, he was engaged in a gunfight and he reacted appropriately.'

Cannito would not elaborate.

About an hour later and 92 miles west of the casino town, police in California say a biker was found shot dead alongside Interstate 40 near Ludlow.

It was not immediately clear whether the death is related to the casino shooting, said Chris Patterson, a spokesman for the San Bernardino Sheriff's Department.

Cannito said the incidents appear to be linked, though he would not elaborate.

The motorcyclist appears to have been shot while riding westbound on Interstate 40, away from Laughlin, said Patterson. 'We believe it's a 29-year-old white male from the San Diego area. He's a motorcycle club member.'
