Group of pranksters break into a Manhattan train's conductor booth to play an ISIS prank

In an apparent prank, two Manhattan subway riders broke into a conductor's booth and identified themselves over the public address system as members of ISIS intent on hijacking the train, police sources said. The suspects, however, slipped off the train at the next stop late and ran off. The sick joke unfolded Thursday night just before 11 p.m. aboard the southbound R train between the 23rd Street and Union Square stations. "They said something to effect, "This is ISIS — We are hijacking the train," a source said.
