A judge Monday sentenced a 22-year-old Lawrence man to serve nine years in federal prison for robbing a Lawrence credit union last year, a U.S. Attorney’s office spokesman said.

U.S. District Judge Carlos Murguia sentenced Timothy Hays after Hays pleaded guilty in January to one count of armed robbery and one count of brandishing a firearm during the July 12 robbery at KU Credit Union, 3400 W. Sixth St.

Prosecutors said Hays brandished a loaded firearm to a teller and demanded money before grabbing cash and leaving through the credit union’s front door, which is near Sixth Street and Kasold Drive. Lawrence police arrested Hays three hours later that day when officers discovered him in the area of the credit union.
