UPDATE: (1:30 PM - A pipe bomb was detonated.   Ocean County Prosecutor's Office spokesman Al Della Fave says "multiple additional devices" were wired to the pipe bomb that was detonated, but the others did not go off.  A 4-block area around the site is on lock-down.

UPDATE: (2:04 PM Ocean County Prosecutor's Office spokesmen Al Della Fave said the race which was scheduled to begin at 9:30 was delayed because so many participants still required registration.  The blast, which occurred at 9:35 AM, would have injured many racers and spectators if the race had started on time.

SEASIDE PARK, NJ - The Semper Fi 5k race was cancelled this morning after an explosion in a plastic garbage can along the race course near D Street at the boardwalk. There were also reports of an unattended backpack at the boardwalk.

Chad Ruedin was taking a walk along the boardwalk when he heard the explosion at about 9:35 AM.  At first, he thought it was the start of the race.  As he approached he saw smoke eminating from the green plastic garbage can, blown out the bottom with peices of plastic all around.  He was moved back from the scene by a sheriff's officer, but not before capturing a photo.  There were no injuries in the blast.

In an interview with News12 New Jersey, Ruedin said some people were saying it looked like someone threw an M-80 into the garbage can.

The Seaside Semper FIve Marine Corps Charity 5K website posted the following notice on their website:
"Out of extreme precaution, this year's Seaside Semper Five has been canceled due to an unidentified suspicious backpack found at the race site.  The safety and security of our participants, spectators, staff and volunteers is of utmost importance."
