PISCATAWAY, N.J. (CBSNewYork) — A former student is in custody after allegedly stabbing two people at the Rutgers Business School in Piscataway on Friday afternoon, police say.

A faculty member and a student were stabbed inside an office on the Livingston Campus around 2:30 p.m., CBS2’s Tracee Carrasco reported.

Two students told CBS2 they heard a woman crying for help.

“It sounded like a struggle, so I thought maybe there was a fight, but it sounded like a girl screaming in pain,” Stephen Mourad said.

“I saw a girl sitting in a chair and professors bringing towels to put on her wound somewhere around here, if I remember, and she was sitting in a chair with paramedics around her,” Nathan Gabriel added.

The Middlesex County Prosecutors Office said the suspect took off after the attacks but was soon taken into custody with self-inflicted injuries.
