TOPEKA, Kan. (AP) — A former Topeka store clerk has been sentenced to two years in federal prison for helping to arrange a robbery of a man who stocked ATMs with cash.

The U.S. attorney’s office says 21-year-old Ahmad Salim Salti, of Topeka, was sentenced Tuesday for conspiracy to commit robbery.

Topeka police were called in September 2014 when a masked gunman brandishing a firearm entered the store where Salti worked just as the victim was beginning to fill an ATM.

The gunman took the money and the keys to the victim’s van before escaping in the vehicle.

Investigators learned that Salti had helped to plan the robbery by providing the date and time the victim would fill the ATM. The robber has pleaded guilty and is awaiting sentencing.
