School principals in Prince George’s County are being asked to review the district’s safety standards after separate security issues at two schools in less than a week.

Superintendent William Hite Jr. said last week that the school district needs to be more vigilant regarding allowing individuals to enter school buildings.

The review comes after a man went into an elementary school in the 8300 block of Oxon Hill Road in Fort Washington last Wednesday afternoon and tried to rob someone.

A man walked into Fort Foote Elementary School about 2:30 p.m. and demanded cash from a secretary who was sitting near the door, according to police and school officials.

Nothing was taken and no one was hurt.

A similar incident occurred Thursday when someone ran into William Paca Elementary School in the 7800 block of Sheriff Road in Landover after allegedly being chased by a group of men. The principal asked the man to leave and police were notified.

Briant Coleman, a spokesman for Prince George’s schools, said letters were sent home with students about both incidents.

Hite sent a letter to all principals containing safety suggestions, including a periodic review of lockdown procedures with the staff; notifying security of suspicious activity in the school; and ensuring that staff members wear identification cards.
