( CNN ) -- A man who is accused of trying to board an Air Jamaica flight at Orlando International Airport with apparent bomb-making materials was taken into custody Tuesday . Witnesses say the man arrested Tuesday was `` rocking left and right and up and down . '' Officials said Kevin Brown , a Jamaican national , was acting strangely and caught the attention of an air safety officer at the Florida airport . Brown was arrested on charges of carrying a weapon or explosives onto a plane , according to the FBI . The bureau said Brown , who is in his early 30s , had baggage that concealed two galvanized pipes , end caps , two containers of BBs , batteries , two containers with an unknown liquid , a laptop and bomb-making literature . `` He looked rather crazy , '' a passenger told CNN affiliate WKMG . `` He was rocking left and right and up and down . '' Transportation Safety Administration officials said Brown caught the eye of a `` behavior identification officer '' about noon Tuesday as Brown approached a ticket counter for his planned flight to Jamaica . Lee Kair , the TSA 's federal security director in Orlando , said the materials in his bags posed no danger to other travelers . Initial record checks indicate that Brown was in the United States legally , the FBI said . The FBI and the Orlando Police Department are investigating , Kair said . Airport officials say several ticket counters were shut down during the incident and 11 flights were delayed . Airport spokeswoman Carolyn Fennell said Air Jamaica , Air Canada , West Jet and Frontier flights were among those delayed . `` Things are slowly returning to normal , '' Fennell said , adding that the terminal where Brown was apprehended was operating normally by 3 p.m. Kair said that behavior identification officers like the one who spotted Brown are plain-clothes officers trained to watch for suspicious behavior at airports . `` When people are doing things that are deceptive , they exhibit behaviors that are involuntary , '' he said . `` Our officers are very well trained to identify these behaviors . '' Brown is scheduled for an initial appearance in federal court in Orlando on Wednesday . E-mail to a friend .
