A man fleeing security drowned early Saturday after he leaped over a railing into a moat surrounding a casino, authorities said.

Police said the man ran away while being questioned about a fake identification card at the Isle of Capri casino.

Authorities were called around 12:30 a.m., and firefighters recovered the man's body about 45 minutes later.

The man's name was not immediately released. Police said only that he was in his early 20s.

It was the second death of its kind at the casino in recent years. In July 2005, police said, a woman apparently jumped into the Isle of Capri moat and later died.

Moats are common fixtures at Missouri casinos. Casino gambling in the state initially was restricted to floating riverboats, but the state's constitution was amended to allow riverboat casinos to float within manmade moats.

Jill Haynes, spokeswoman for St. Louis-based Isle of Capri Casinos Inc., did not immediately return calls seeking comment Saturday.
