New York lawmakers are calling for more pro-Palestinian protesters to be disciplined after police arrested nine Wednesday during a takeover of the Barnard College library. Congressman Ritchie Torres said the private college should expel student protesters after some tried to keep administrators from leaving the building during a bomb threat.

Some protesters were arrested for failing to leave the premises after they were made aware of an active bomb threat on the building.

Approximately 50 pro-Palestinian protesters occupied the Barnard Milstein Library Wednesday afternoon, police said.
