School safety agents at Norman Thomas High School in Manhattan were commended for preventing a student — who turned out to be a teenaged crime wave — from sneaking a loaded gun into the school at 111 E. 33rd St.

SSA Level 3 Frankienette Roberson said the incident occurred at about 9 a.m. June 9 when the student was trying to enter school.

As he was passing through an xray machine operated by SSA Crystal Summers and a walk-through monitored by SSA Bernard Smalls, the youth lit up the machines. The agents directed him to SSA Lawrence Booker who was handscanning those entering.

Booker waved the scanning wand over the youth, detected a handgun, and immediately stopped the student at the door and notified officials. Roberson, SSA Level 3 Quinn Beauford, Supervisor of School Safety Pedro Reyes and SSA Derrick Singleton, came to investigate and secure the area.

The student and his gun were turned over to detectives from the Midtown South Squad. Under questioning, the youth told them the gun was stolen from a home in the Poconos in Pennsylvania and that he had committed seven burglaries there and one in the area covered by the 24th Precinct.
