SALT LAKE CITY — The FBI was looking Thursday for a serial bank robber suspected in five robberies in Utah and Idaho.

Since Dec. 21, four banks in Idaho — mainly around the Boise area — and one in Cedar City have been robbed, allegedly by the same man. The robberies include:

• Dec. 21, 2012 -  Chase Bank, Boise

• Jan. 4, 2013 - Washington Trust Bank, Garden City, Idaho

• Jan. 22, 2013 - Wells Fargo Bank, Boise

• Feb. 26, 2013 -  Mountain America Credit Union, Cedar City

• March 6, 2013 -  U.S. Bank, Boise

The Cedar City robbery prompted a temporary lockdown of a nearby middle school.

In each incident, the man walked up to the counter and demanded cash or displayed a note, according to the FBI. The suspect is believed to be between 50 and 60 years old, about 5 feet 10 inches tall, weighing between 145 and 180 pounds. He has gray hair and in one of the Boise robberies was seen wearing a beard that investigators believe was fake.

Anyone with information about the man is asked to call the FBI at 801-579-1400.
