NYPD: Suicidal Man Causes Subway Terror Scare

Police say a suicidal Manhattan college student caused a brief terror scare by carrying cyanide into a subway tunnel.

Track workers spotted the 20-year-old man early Friday in a tunnel under the East River. Police later discovered he was carrying a backpack holding a container of highly toxic sodium cyanide.

The NYPD initially suspected the man might have been part of a terror plot. But the suspect convinced investigators that he was planning to kill himself by swallowing the chemicals.

He was not immediately charged.
