A subsequent search of the apartment turned up a mask and clothing believed to have been used in the robberies, as well as a small amount of marijuana.
The man is believed linked to at least three bank robberies one in Salt Lake City and two in South Salt Lake last month.
On July 11, a man wearing a transparent Halloween mask entered the Zions Bank branch at 910 W. 2100 South in Salt Lake City, brandishing a black handgun. He demanded and received an undisclosed amount of cash and fled on foot.
On July 18, the same suspect is believed to have held up a US Bank branch at 2700 S. 300 West in South Salt Lake. A week later, the robber also is thought to have hit a Zions Bank branch at 3900 S. 700 East.
Keller said the suspect was booked into the Salt Lake County Jail where he was being held without bail on suspicion of three counts of first-degree felony aggravated robbery and one third-degree felony count of marijuana possession.
A probable cause statement notes that an unidentified witness told investigators that the suspect had displayed large amounts of cash on the days corresponding to the robberies. The statement also notes that after being advised of his right to remain silent, the suspect acknowledged he was a drug dealer.
The Salt Lake County District Attorney is screening the cases.
