The Trolley Square shopping center was evacuated about 9 p.m. Thursday after a cell phone caller told Salt Lake police dispatchers a bomb had been planted in the area.

The caller spoke of Jihad and furthering a holy war, said Salt Lake Police Lt. LaMar Ewell.

Mall authorities closed and evacuated the shopping center, and police asked shop owners to search their shops. Police also searched common areas for unusual circumstances, Ewell said.

By 10 p.m., no bomb had been found and there had been no explosion. Shop owners were allowed back into the mall to properly close down their stores, Ewell said.

Meanwhile, police tracked the cell phone number from which the bomb threat came. Officers believe the call originated near Liberty Park, Ewell said.
