Dismissals of several Prince George’s County schools were delayed Tuesday afternoon while police dealt with a barricade situation in the area, authorities said.

The barricade in the Landover area of the county began about 2 p.m. and ended peacefully a couple of hours later, authorities said. No shots were fired and one person was taken into custody, police said.

A school system spokesman said he understood that the barricade was near Brightseat Road. Buses were detained at schools where dismissals were scheduled while the incident was going on.
