Just before Ocala's Paddock Mall was set to open Monday morning, someone called the police department saying six different explosive devices had been planted around the property.

Call to 911: "The bombs are going to go off in two and a half hours from now, soon I will go the mall and shoot everyone, I have a gun."

The mall was evacuated, and customers were turned away as they arrived.

“Your malls, schools anywhere there is potentially a large number of people, it could be devastating," said Sgt. Angy Scroble with Ocala Police. "We are going to respond immediately and take every precaution that is necessary.”

But you could tell from the automatic weapons responding officers carried, bombs weren’t the caller's only threat.

“It was someone who sounded angry and also threatened to come and shoot people at the mall,” Scroble said.

As all this was happening, another bomb threat came in, forcing searches of the downtown area. And it was just a couple hours earlier the bomb squad was called in when a park ranger found a suspicious device along Broadway Street.

"It’s probably in the minds of our supervisors and officers on the road that, 'hey we found a device that could have been an explosive device, let’s go with even more caution and more aggression getting people out in the area'," Scroble said.

The device found downtown was detonated and determined to have been a hoax device. No explosives were found at the mall and it reopened a little after 1 p.m. Monday afternoon.

Police promised additional security as they search for the person who made the bomb and shooting threats, and say he could face very serious charges.
