Boston police cleared a protest encampment at Northeastern University on Saturday, and arrested more than 100 people.
Officers could be seen placing zip ties around the protesters' wrists in the morning.
Later other individuals gathered and linked arms as they chanted, obstructing one of the driveways used by police vehicles, including vans transporting the arrested protesters.
The overall number of protesters in the vicinity seemed to increase as the day progressed.
Roughly 102 protesters arrested and will be charged by the Northeastern University Police Department with trespassing and disorderly conduct, state police said in a statement obtained by WCVB5.
University officials said later in a statement that arrested students were released, but the status of the charges against them was not immediately revealed. The statement claimed campus protests had been "infiltrated" by outsiders.
"What began as a student demonstration two days ago was infiltrated by professional organizers with no affiliation to Northeastern," said the statement, which denounced "virulent antisemitic slurs" at the protests.
Several human rights organizations, including Jewish Voices for Peace, raised concerns about the actions taken on Saturday morning.
"We denounce Northeastern University's discipline of student activists and the Boston Police Department's arrest of peaceful protesters," JVP said in a statement.
"We denounce false claims from the Northeastern administration that protests were 'infiltrated by professional organizers' who used 'virulent antisemitic slurs.'"
By "using the actions of counter protesters to slander their own students, the Northeastern University administration is acting in incredible bad faith," the group added.
