BBC interview with Columbia protester shut down by police

Speaking from the window of a campus dormitory at Columbia, a protester was explaining to the BBC what had happened when a police officer intervened.

She was in the middle of describing how police had manhandled students during arrests when an officer approached and closed the window so she could not be heard.

Earlier she had been at Hamilton Hall when "about 80 to 100" police officers stormed the building.

"They barricaded the doors and had about two or three officers stationed in each door so we couldn't get out - which is illegal on its own," she told reporter Alex Lederman.
