Adrian Arambulo of CBS station KLAS in Las Vegas reported on The Early Show that Daryl Williams, 18, faces felony robbery and battery charges and police hope the surveillance tape will lead to other arrests.
Detectives are also investigating whether the group responsible for the 2:20 a.m. Saturday attack near the MGM Grand hotel-casino was responsible for an attack about 40 minutes later at an off-Strip motel. And the crime wave continued into Sunday morning, said Arambulo, with a series of robberies and then another swarming, attacks in which police say the suspects move like a pack of wolves.
"We're not sure at this point, but they could be related," police Sgt. Chris Jones said.
The surveillance video released by police Monday and aired widely on Las Vegas-area TV stations Tuesday showed the casino employee being punched, hit with a belt or chain, beaten and kicked by a mob of people in a driveway next to a hotel staff golf cart.
"The amount of suspects is unusual, and the amount of violence, where they are feeding off one another," said police Lt. Ted Snodgrass.
The victim, whose name and age were not released, was able to rise from the pavement after the mob left. But he suffered a broken jaw and a broken collarbone, police said. Hotel spokesman Gordon Absher said Tuesday the man was recuperating at home.
Las Vegas police Capt. Dave O'Leary characterized the mauling as "truly egregious" and said investigators believed the male and female assailants were in their late teens or early 20s.
Officials don't necessarily believe there is one group of suspects, says Arambulo, but perhaps several groups of suspects that know each other. At this point, they do not think gang members are involved.
