NEW ORLEANS (AP) — Police investigating a spree of overnight armed robberies in New Orleans have arrested four teenagers.

Saturday’s arrests came after four holdups — one in the French Quarter, two in the Bywater area and one in the Marigny neighborhood of New Orleans.

The four have been booked in one of the holdups. An investigation of the other three robberies is ongoing. And the police department is working to see if the four suspects were involved in holdups in other parts of New Orleans.

Two of those arrested were 15 years old. A 17-year-old and an 18-year-old also were arrested.
