NYPD officers tore down tents inside a Fordham University building on Wednesday, 1 May, as they cleared a Gaza protester encampment.
Police escorted demonstrators away from the Lincoln Center campus.
NYPD Deputy Commissioner Kaz Daughtry said "individuals who refused to disperse from the unlawful encampment... [were placed] under arrest."
Fordham University requested NYPD assistance, she added.
It came amid similar action staged at other universities across the US; police arrested more than 130 demonstrators early Thursday at UCLA.
Pro-Palestine encampment protests have also spread to the UK.
