WASHINGTON — Annapolis and Anne Arundel County officials are investigating  a set of bomb threats made against local businesses on Saturday.

Maj. Scott Baker, a spokesman for the Annapolis Police Department, said bomb threats demanding money were made over the phone in a 15-minute time span.

No bombs were found and no injuries were reported.

In Annapolis, calls were made to the SunTrust Bank on Main Street and the Giant supermarket on Bay Ridge Road. Baker said Main Street was temporarily shut down.

“There wasn’t a device on Main Street,” Baker said, noting that police were double-checking to make sure. “The Giant has already been cleared for any device.”

A nonspecific threat also was made in Anne Arundel County,  police said.

Annapolis police, Anne Arundel County police, Maryland State police and the FBI were trying to determine who made the phone calls.
