Gang Participation & Recruitment – On December 6, a School Resource Officer (SRO), with assistance from detectives of the Gang Unit, concluded an investigation resulting in charges being placed against a juvenile in connections to allegations of alleged gang recruitment occurring at Osbourn Park High School located at 8909 Euclid Ave in Manassas (20111). Last week, the SRO at Osbourn Park High School was informed of possible recruitment activity involving the criminal street gang Mara Salvatrucha, commonly known as MS-13. This information was obtained through students and staff at the school. During the investigation, the SRO was able to identify three of the recruiters as juvenile students who attend the school. Following the investigation, the juveniles were charged. The investigation continues. Parents can learn more about recognizing and preventing gang involvement by reading the Parents Guide to Gangs, an informative publication produced by the National Gang Center.
