A bomb threat forced a three-hour evacuation of a Bon Jovi concert at the BankAtlantic Center in Sunrise [Florida] as authorities swept the massive arena for explosives.

The threat turned out to be a hoax, courtesy of someone calling from a cell phone with only 911 capabilities, authorities said. It was unclear if Sunrise police had any suspects. Police did not return numerous messages and pages seeking information Saturday evening.

Sunrise police received the threat sometime around 6 p.m. from a caller saying they would blow up the arena with two bombs at 7:57 p.m., said Sunrise Commissioner Sheila Alu. She said the police had several bomb-sniffing dogs sweeping the arena. “We are taking this very seriously to ensure the safety of all concertgoers,” Alu said.
