NEW YORK -- Two subway riders broke into the conductor's booth of the R train in Manhattan Thursday night and identified themselves over the loud speaker as members of ISIS with an intent of hijacking the train, police say.
The suspects then got off the train at the next stop.
The incident, which is believed to have been a prank, happened around 11 p.m. on the southbound R train between the 23rd and Union Square stations.
The train stopped at Union Square where it was taken out of service and investigators dusted for fingerprints and searched for evidence.
Officials do not believe there was any real threat.
