A man committed suicide on Friday by leaping off a ledge at the newly-built Cosmopolitan hotel and casino onto the famed Las Vegas Strip, police said.

Witness accounts place the man on a ledge at either the 6th floor or the 14th floor of the Cosmopolitan, the newest hotel and casino to open on the Strip, Las Vegas Metropolitan Police spokesman Marcus Martin said.

The hotel, which opened to much publicity on December 15, has 50 floors and nearly 3,000 rooms.

Marcus said police received calls that a man, who was not identified, was threatening to jump from the Cosmopolitan at about 4:45 a.m., Martin said.

Officers arrived shortly thereafter and tried to negotiate with the man, but he didn't respond and at 6:26 a.m. jumped to his death.

Martin said that suicides on the world-famous Strip are not common.

"The last thing the Strip and Las Vegas need is to be known as a suicide haven," he said.
