LAS VEGAS - Police are trying to determine what sparked an incident that led to the shooting death of a man in a sports book on the Las Vegas Strip.
Shocked gamblers fell to the floor as shots rang out just before noon Monday in the sports book at the Stardust hotel-casino.
Las Vegas police said three shots were fired, with one hitting the 56-year-old victim in the chest. He died a short time later at a local hospital.
The victim's name was being withheld pending notification of relatives.
Police say Anthony Cuccia, 59, was arrested and booked into the Clark County Detention Center on a charge of murder with a weapon.
After shooting the victim, the gunman handed his weapon over to a hotel security guard and stayed until police arrived.
Police did not reveal a motive in the shooting, although some customers said it may have resulted from a dispute over some bets.
The sports book and north entrance of the hotel were closed for about five hours after the shooting before being reopened.
''The employees are just in shock,'' Stardust spokesman Jim Seagrave said. ''It's kind of business as usual, but it's not fun.''
At the same time police were investigating the Stardust shooting, other officers were at the nearby Westward Ho motel, where a man threatened to kill himself with a knife. The man later surrendered to police.
