New Jersey ? Two terrorism suspects arrested at an airport over the weekend ran afoul of school officials and law enforcement over the last several years, with one considered so disruptive that he was removed from school and taught privately with a security guard present.

Mohamed Mahmood Alessa was placed on “home instruction” three months after transferring from an Islamic high school in 2004, North Bergen High School spokesman Paul Swibinski said.

Swibinski declined to say what made officials consider Alessa to be dangerous, but said it was not a specific incident or physical altercation, but more a pattern of behavior.

Authorities say Alessa, 20, and Carlos Eduardo Almonte, 24, tried to fly out of New York’s Kennedy Airport on Saturday in hopes of getting terrorism training in Somalia.

Alessa, who was born in the United States, is the son of Palestinian immigrants. Almonte is a naturalized citizen who was born in the Dominican Republic. Both are Muslim.
