MIAMI – A man was arrested Wednesday afternoon at Miami International Airport, airport officials announced on Twitter.

Miami-Dade Aviation Department spokesman Greg Chin said the man was making threatening remarks at the Concourse D check-in area.

"He just walked in with no bags or nothing and just started screaming," one witness, Orlando Perez, said.

Local 10 News reporter Terrell Forney was inside Concourse D at about 12:30 p.m., when he said multiple Miami-Dade police officers held the suspect down as he screamed and cursed at them.

Forney said witnesses claimed that the man tried enter a baggage area where American Airlines employees work.

"He walked in there where people were checking their bags and just started screaming," Perez said. "They just started screaming back and forth, and then I saw one of the TSA guys say, 'Call the cops,' because he was screaming louder and louder and louder."

Forney said the suspect's hands and feet were bound as he was detained.

"They held him down, but he didn't want to be held down and it took like four or five cops -- it took a little while," Perez said.

Operations inside of the airport were unaffected as passengers continued to filter through.

The heavy police presence, however, created a traffic nightmare for vehicles arriving to the airport.

Meanwhile, the man who caused the disturbance had to be physically carried outside by officers, where paramedics were waiting to treat and transport the man, who sustained some injuries during the takedown.

"He started fighting one of those customs agents -- the guy with the white hair," Perez said.

The suspect's identity has not been released.

It's unclear what led to his outburst.
