ANN ARBOR, MI - Police are investigating a bomb threat at the Jewish Community Center of Greater Ann Arbor.

A staff member called police about 9:20 a.m. Monday, Feb. 27 to report the threat at the Hebrew Day School at 2937 Birch Hollow Drive, said Ann Arbor police Detective Lt. Matthew Lige.

The staff member told police that a male caller called the school, located at the center, and said there was a bomb in a backpack and that it would be detonated, Lige said.

The center was evacuated and the about 200 students and staff members were taken to an off-site location, Lige said. Police are working with the FBI and Michigan State Police, and bomb-sniffing dogs were searching the premises as of 11:15 a.m.

Shortly before noon Lt. Lige said the search has been completed and no explosives or suspicious packages were found. Students are being allowed back into the building.

Because of the specific nature of the threat, Lige said the approach was different than a typical bomb threat. Now that the school has been swept and no explosives were found, AAPD will begin working with the FBI to determine who made the call.

Birch Hollow Drive is closed at Stone School Road and the surrounding neighborhood has been blocked off.

Lige said similar threats were called in across the country Monday, but it was not immediately known if there was a direct connection. The Indy Star reports that a similar threat was made the Indianapolis JCC.

The JCC centers in Harrisburg and York, Pennsylvania have also been evacuated today for bomb threats, according to a report from Pennlive.com
