Chicago Public Schools is expanding its team of traveling security officers so the district has more available to staff potential hotspots.
Team members will be stationed temporarily at schools to augment security already in place.
CPS spokeswoman Monique Bond would not say how many officers are being added, or how many are currently on the force, but staffers say over the past few weeks their team has grown from its original nine members to about 20. They said more hiring is scheduled.
Chicago schools chief Ron Huberman ordered his new safety and security director to make the move, Bond said.
"There's going to be more of a strategic focus on the deployment of the resources," Bond said. "There are certain schools where we know there could be problems that could arise. We know we're going to have an activity after school or a sporting event."
In September, 16-year-old Fenger High School student Derrion Albert was beaten to death in a brawl outside the school that stemmed from tensions between students from two neighborhoods.
