Story highlights The explosion is being investigated by the Joint Terrorism Task Force as a possible terrorist act

No injuries were reported, but the charity run was canceled

(CNN) An explosion in a garbage can near a Marine Corps charity run in New Jersey is being investigated as a possible terrorist act, authorities told CNN Sunday.

Saturday's blast was likely timed to disrupt the event in Seaside Park, officials said. No injuries were reported -- most likely because registration problems delayed the start of the race, so no one was near the garbage can when the explosion happened.

Investigators discovered three pipe-bomb-type devices wired together near the boardwalk, authorities said. An initial examination showed the devices were rudimentary, with some type of timer, and only one of them detonated, two federal law enforcement officials told CNN.

Investigators said they found similarities between this device and the bomb that exploded in New York's Chelsea neighborhood Saturday evening, but are not linking the two events at this time.

The devices in New Jersey and New York both used cell phones as timers, officials told CNN.
