NEW ORLEANS (AP) - New Orleans police have arrested four suspects in a shooting incident that led to the three-hour lockdown of Medard H. Nelson Elementary School.

A police spokesperson says the last suspect, 21-year-old Ronald Decou, was arrested Wednesday evening.

He was booked on two counts of attempted first-degree murder and one count of simple burglary.

Police Superintendent Ronal Serpas said the incident began Wednesday afternoon after officers answered a call about suspicious persons in the area near the school.

When police arrived, the four men ran; one may have fired a weapon at the officers.

Police arrested 20-year-old Joseph Smith, 20-year-old Delmonico Williams and a 17-year-old at the scene.

No injuries were reported.
