Florida ? A device similar to a pipe bomb exploded early Monday in a trash can at a remote Walt Disney World parking lot, authorities said. No one was injured and no serious damage was reported in what officials believe was an isolated incident.

Orange County sheriff’s deputies responded to a 12:30 a.m. call from Disney. An employee heard a loud noise and saw white smoke coming from the can near the Downtown Disney shopping and entertainment district, Sheriff Kevin Beary said.

“We have recovered a very crude, homemade, low-level device,” Beary said. “Because of the time and location of the event, we do not believe this incident was designed to cause significant property damage or injury. We also believe this is an isolated incident.”

Beary said investigators were still trying to determine what the device was made of, but “end caps” typical of pipe bombs were found.
