A bomb scare blamed on a passenger who had been drinking

A bomb scare blamed on a passenger who had been drinking caused a five-hour delay in Sunday's return to Port Canaveral for the Carnival Cruise Ship Sensation, authorities said.

No bomb was found and Brevard County deputies arrested a Virginia man accused of starting the scare.

The ship was on its way back from Nassau, Bahamas, early Sunday when witnesses heard the "highly intoxicated" passenger say that "a bomb was about to explode," and "We are Jihad," said U.S. Coast Guard Petty Officer 1st Class Christopher Evanson.

"In 2010, in today's age, you can't take that lightly," Evanson said.

The Coast Guard, FBI and Brevard deputies boarded Sensation at about 9:30 a.m. and after interviewing witnesses and the suspect, determined there was no bomb. Ibrahim Khalil Zarou, 31, was arrested at 10:15 a.m.

He was being held Sunday night on a charge of falsely threatening to detonate a bomb, Brevard jail officials said. Bail was set at $10,000.

Although the delay complicated connections for some the Sensation's 3,470 passengers, "You can't put a time [limit] on safety and security," Evanson said

A sheriff spokesman said the case is being turned over to the Coast Guard and FBI.
