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.

Nine protesters were arrested at the scene as dozens of NYPD officers entered the library. The bomb threat was deemed not credible.
