ORLANDO, Florida (Reuters) - The FBI arrested a Jamaican man on Tuesday on charges he tried to board a plane at Orlando International Airport with pipe b**** components and instructions in his checked luggage.

The agency identified the man as Kevin Brown, 32, who was ticketed for Air Jamaica flight 80 from Orlando to Montego Bay, Jamaica.

In a search of Brown's luggage, agents found two galvanized pipes, end caps, two small containers of air gun pellets, batteries, two containers of an unknown liquid, a laptop computer and b****-making literature, according to a statement from Steven Ibison, special agent in charge of the FBI's Tampa division.

Initial record checks indicated Brown was in the United States legally, the FBI said. Brown is scheduled to make a first appearance on Wednesday in U.S. District Court in Orlando on charges of carrying a weapon or explosive on an aircraft.

The Transportation Security Administration said a "behavior detection officer" keeping watch for suspicious activity singled out Brown for closer inspection.

Airport spokeswoman Carolyn Fennell said Brown was detained while preparing to check his luggage for his flight.

His luggage was searched, he was taken into custody by Orlando Police and then turned over to the FBI, which announced the charges late on Tuesday.

Passengers were evacuated from a section of the airport terminal around the Air Jamaica, Air Canada and Air Frontier ticket counters and 11 flights were delayed, Fennell said.
