A Philadelphia teenager pleaded guilty in juvenile court to using his Twitter account to intimidate a crime victim.
Nasheen Anderson, 17, pleaded guilty Wednesday in Family Court to witness intimidation and terroristic threats.
He used Twitter to post a photo of the victim and copies of secret investigative documents related to a 2012 attempted shooting.
Police initially suspected the teenager was linked to a now-defunct anonymous Instagram account called rats215, which posted witness' photos next to statements they gave police. Prosecutors said the investigation continues but the teen isn't accused in that case.
Assistant District Attorney Jan McDermott denied the Commonwealth's request that Anderson be tried as an adult.
McDermott said she would ask for "a significant period of confinement'' to a juvenile treatment facility when he is sentenced Dec. 16.
