The man in custody is identified as Mansor Mohammad Asad, 43, who authorities say posed no potential security threat.

Miami-Dade police say he caused enough of a ``disturbance'' that the pilot had to return to the jet-bridge. When Asad was taken off the plane to be interviewed by police, he threatened officers, made racial comments and charged an officer, authorities said. He was Tasered twice.

Asad was charged with threats against a public servant, disorderly conduct and resisting an officer without violence to his person.

The action taken by officials on the Delta Airlines flight comes at a time of heightened security at U.S. airports following the foiled terrorist attempt by a Nigerian to blow up an airplane on Christmas Day.

FBI spokeswoman Judy Orihuela said the bureau was notified and concluded it was a local police matter. Also on Wednesday, military jets escorted a Hawaii-bound flight back to the Portland, Ore., airport due to a disruptive passenger. There was no known link to terrorism in that case, the FBI said.

The Anti-Defamation League, in a statement Thursday, said it was ``deeply disturbed by the alleged anti-Semitic rant by Mansor Mohammad Asad,'' Andrew Rosenkranz, the Florida regional director, said. ``Such comments point out the fact that anti-Semitism and hatred of Jews is still very much a part of society.''

The Miami incident unfolded Wednesday when the crew aboard the flight, scheduled to leave at 5:45 p.m. from Miami International Airport, decided to return the flight to its gate.

Homeland security officials said Wednesday that four passengers were taken off the plane. A police offense incident report says Asad was traveling with three people, including his daughter, his sister and his girlfriend.

Asad's son, Mickey Asad, who was not traveling with his father, told The Miami Herald his father has bipolar disorder. He told the Associated Press the elder Asad had been in and out of mental institutions when he was younger.

``It's not what it's made out to be,'' Mickey Asad told The Herald. ``I don't know, someone had to have pushed his buttons. I don't know, I couldn't explain honestly. Of course he's not a terrorist.''

The father had been on vacation in Miami, he added. Asad is an American citizen who works at Appliance Connection on Lagrange Street the arrest report said.

After the passengers were removed, those onboard were rescreened and the flight was cleared for departure.

According to Miami-Dade police reports, here's what happened:

The plane was taxiing when a flight attendant alerted the captain of a passenger ``talking in a loud tone of voice and stating that he is Palestinian and that he wanted to kill all the Jews.''

As the flight attendant tried to give instructions before taking off, Asad, who was in seat 14-A, was loud once again. He was drinking a beer, apparently from the first class cabin where his daughter was seated.

At points Asad was speaking in a foreign language, thought to be Arabic.

He made several derogatory statements about Jews, the report said.

He was taken off the plane and searched, police said. While they tried to search him, he berated officers and made racist comments.

According to the arrest affidavit, Asad said: `` `I'm not afraid of you cops. I've gotten in fights with cops in Ohio and broke their arms in three places. I've broken skulls too!' ''

He then prayed and chanted, before telling a cop to ``Go back to Africa, you white racist cop!''

Asad was searched, but officers did not find any weapons or explosives.

During the search, his socks and shoes were removed. An officer took off Asad's right handcuff so he could put them back on.

When the officer did that, Asad once again started yelling at the officers.

He ``stood up and rolled his sleeves up. He then clenched his fists and charged,'' toward an officer, the report said.

He wouldn't stop and an officer used a Taser on him. Asad fell to the ground, but did not listen to officers' commands and then tried to stand up. A Taser was used a second time.

He was then handcuffed and taken to the jail.
