PHILADELPHIA (CBS) — Counselors and more school resources officers will be at Carver High School in North Philadelphia on Tuesday after police say an Instagram user by the name of “Carverkilla” posted a picture of guns and a threat to “shoot up” the school.

The Instagram user made the treat at 2 p.m. Monday.

The school went on a partial lockdown until the school district determined there was no immediate threat.

In a letter to parents, the school says they’ve identified a suspect and that police hope to have the suspect in custody soon.
