The Atlanta school district has hired the leaders of its new, in-house police force.

The new, 82-member force will replace the Atlanta Police Department officers who staff Atlanta schools.

The new police force is expected to cost about $8.4 million, slightly less than the district currently spends.

Marquenta Sands Hall, APS’s current security director, will serve as executive director of the new department.

Ronald Applin, a former Fulton County Sheriff’s Office captain, will serve as police chief.

And Ralph Velez, who currently oversees a North Carolina community college police force, will serve as operations director.
