The Department of Homeland Security (DHS) on Wednesday announced ICE had detained a Harvard Law School professor accused in a shooting outside a synagogue in October.
Carlos Portugal Gouvêa, a Brazilian national, was arrested Oct. 2 after he allegedly fired a BB gun outside a Boston area synagogue the day before Yom Kippur.
Gouvêa told authorities at the time he was "hunting rats."
Gouvea was put on six months of pretrial probation for a misdemeanor charge of illegal use of the air rifle, while his other charges of disturbing the peace, disorderly conduct and vandalizing property were dismissed.
The Harvard Crimson temporary non-immigrant (J-1) visa.
"It is a privilege to work and study in the United States, not a right," DHS Assistant Secretary Tricia McLaughlin wrote in a statement. "There is no room in the United States for brazen, violent acts of antisemitism like this. They are an affront to our core principals as a country and an unacceptable threat against law-abiding American citizens."
McLaughlin added DHS is "under zero obligation to admit foreigners who commit these inexplicably reprehensible acts or to let them stay here."
"Secretary [Kristi] Noem has made it clear that anyone who thinks they can come to America and commit anti-American and antisemitic violence and terrorism should think again," she wrote. "You are not welcome here."
Gouvêa was a visiting professor of law at Harvard, and his full-time position was as an associate professor at the University of São Paulo Law School and CEO of IDGlobal in Brazil.
The university website noted he led research that shaped major Brazilian Supreme Court decisions, documented violence against Indigenous peoples and participated on the boards of several Brazilian companies, including the Fulbright Commission, Brazilian Students Organization, Generation and Sempre SanFran.
Harvard did not immediately respond to Fox News Digital's request for comment.
