Authorities in North Jersey are investigating two alleged sexual assaults at Clifton High School. Clifton police have arrested a 17-year-old male for allegedly coercing a 16-year-old female student to have sex with him on two occasions. He now faces six felony charges, including two counts of sexual assault and two counts of criminal coercion. Both incidents happened this month inside Clifton High School.

Police say the two started a relationship over the summer on Facebook. The female accuser claims the male student recently began to threaten her, and eventually blackmailed her into having sex with him.
