A Casper man charged in an attempted robbery has entered a plea in his case.

Justin Eberhardt pleaded not guilty to charges of aggravated robbery and aggravated assault.

Casper police say in January, a woman arrived at a coworkers house with a bank bag from her place of employment.

Investigators say a man wearing a mask approached her and demanded the money at gunpoint.

Neighbors chased the robber away, and he fled in a vehicle that was later found by police.

A search warrant was executed on the vehicle and a nearby house, where officers found the mask and the gun and linked Eberhardt to the items.

He remains jailed on twenty-five thousand dollars bond, awaiting trial.
