A 21-year-old man has pleaded not guilty in federal court to charges he robbed a Lawrence credit union last week.

A federal grand jury in Kansas City, Kan., had indicted Timothy Hays on charges of armed bank robbery and using a firearm during the robbery.

Prosecutors allege Hays took money from a teller July 12 at KU Credit Union, 3400 W. Sixth St., after displaying a loaded gun. The credit union’s accounts are insured by the National Credit Union Administration Board.

Lawrence police had released surveillance photos of the suspect and eventually arrested Hays in the area hours later.

Hays is next due in court Aug. 23 in front of U.S. District Judge Carlos Murguia.

If convicted, Hays faces a maximum 25 years in prison on the bank robbery charge and five years to life imprisonment on the charge of using a firearm during the alleged robbery.
