Two banks within 10 blocks of each other were robbed Thursday afternoon by a bandit wearing a wig.

Investigaters from Salt Lake police and the Salt Lake County Sheriff's Office are probing the similarities in the late afternoon heists that happened within 20 minutes of each other.In the first robbery, the bandit entered the Zions National Bank at 3800 S. 700 East just after 3:30 p.m. and demanded cash.

Sheriff's Sgt. Jim Potter said a gun was seen in the waistband of the man's pants. The man fled on a mountain bike.

At 3:52 p.m., the First Security Bank at 1255 E. Brickyard Road (3300 South) was robbed by a man who said he had a gun but didn't display the weapon.

Salt Lake Police Lt. Dan Tueller said the man then left the bank, but no one reported seeing if he left on a mountain bike or by some other method.

In both robberies, the suspect is described as a caucasian male in his 20s, about 5 feet 11 inches tall, thin build and wearing a curly white or blonde wig.
