FBI agents were searching Thursday for a man who robbed a downtown bank Wednesday.

Their investigation, however, may be slowed because the bank's camera system was not functioning.Salt Lake Police Lt. Norm Thompson said the bandit walked into Home Savings and Loan, 116 S. Main, about 11:35 a.m. and handed a teller a note that read: "This is a holdup. I've got a gun."

After the teller filled a brown paper sack with about $1,800, the bandit fled south on Main Street. Police later recovered from a nearby dumpster a plaid shirt believed to belong to the bandit.

Thompson said the bank's alarm system and cameras had malfunctioned, so the FBI will have no photograph that will help to identify a suspect.

Witnesses described the bandit as Caucasian, about 24 years old, about 5 feet 9 inches tall, weighing about 120 pounds. He was clean-shaven and had hazel eyes, freckles and brown hair that was cut in a "flat-top" style. He wore a light-colored plaid shirt and gray pants.
