More details from NY1 about the demonstration in front of the Secondary School for Law, Journalism and Research in Park Slope, which is in the old John Jay High School building on Seventh Avenue.

Police and students scuffled outside a Brooklyn high school Wednesday during a demonstration against the school’s enforcement of a ban on cell phones.

Five students were arrested during the rally outside the Secondary School for Law, Journalism and Research in Park Slope. Four were charged with disorderly conduct and one with assaulting an officer.

In all, about 150 students had walked out of their classes to protest the ban, which has been on the books citywide since 1987.

The students said they need their phones in case of emergency.

They were also upset about new security measures which they say slow them down when they’re trying to get into the building.
