The daughter of U.S. Rep. Ilhan Omar, D-Minn., was arrested Thursday in connection with protests at Columbia University, law enforcement sources told Fox News. 

Isra Hirsi was in the custody of the New York Police Department and put into flex cuffs or zip ties and will face trespassing charges, according to sources.

Earlier in the day, Hirsi said she was suspended from Barnard College, located near Columbia, for "standing in solidarity with Palestinians facing a genocide."

"Those of us in Gaza Solidarity Encampment will not be intimidated," she wrote on X. "We will stand resolute until our demands are met. our [sic] demands include divestment from companies complicit in genocide, transparency of @Columbia’s investments and FULL amnesty for all students facing repression."

Dozens of anti-Israel activists began protesting at Columbia University on Wednesday morning, creating an encampment on the main lawn in protest of Israel's war against Hamas. Fiery protests continued into the overnight hours with calls for an intifada and the death of Israeli Prime Minister Benjamin Netanyahu.

On Wednesday, Omar questioned Columbia administrators during a congressional hearing on Capitol Hill about anti-Israel activism on the Ivy League campus. 

During the hearing, Omar sounded the alarm about what she called an "attack" with a "toxic chemical substance" at an anti-Israel protest at Columbia University. However, according to court documents, the substance was a non-toxic flatulence spray called "Liquid A--" and "Wet Farts." 

Fox News Digital has reached out to Omar's office. 

Rep. Jamal Bowman, D-N.Y., suggested that Hirsi's suspension was a reprisal for her mother's questions.
