EDISON - Police say there is no evidence that a teen found with explosives at his Edison home intended to harm anyone with the devices, but it is still unclear what his plans were.

New pictures have been released showing what police say are parts of homemade bombs found in the bedroom of a 16-year-old Edison High School student. The explosives were found as police followed a tip while investigating four bomb threats made to the school.

Officers say they found fireworks, shotgun shells and makeshift devices containing gun powder and fuses Sunday night at the student's Harmon Road home.

The student has been charged with possession of explosive devices and suspended from school. The boy was released to a family member. His name was not released because he's a juvenile.

Edison Police Chief Thomas Bryan, however, says he doesn't believe the charged student had anything to do with the bomb threats. The threats remain under investigation.
