Jan 2, 2013

On January 2, the Orange County Sheriff's Office was called by Walt Disney World custodial staff when they found what appeared to be hand grenades. The suspicious objects were found near Downtown Disney, at 1780 Buena Vista Drive. The bomb squad came, but determined that the grenades were hollowed out and were not dangerous. They were to be taken away and "rendered safe."
