Someone near the jungle gym at the park off Jefferson Street and Marron Road called Carlsbad police about 2:10 p.m. Saturday and reported the package, which was described as a medium sized brown box that had batteries and black and red wires protruding from inside, Carlsbad police Lt. Bruce May said.
Officers evacuated the park, closed the 2200 block of Jefferson Street and called for the San Diego County Sheriff’s Department Bomb/Arson Unit to investigate, May said.
Shortly after 3:30 p.m., Bomb/Arson Unit personnel used a high velocity water cannon to destroy the package, May said. They determined the box contained improperly discarded nickel cadmium batteries, he said.
Police officers collected the batteries and sent then for recycling, May said, adding that whoever left the batteries had not been identified but no further investigation was necessary.
