The Juneau Police Department is trying to identify a suspect in a robbery reported Sunday morning, according to a release from the department.

JPD learned of the robbery at about 5 a.m. Sunday, the release states.

The victim told police a man walked into a business in the 400 block of Willoughby Avenue and demanded money. After the victim refused, the robber lifted his shirt and grabbed what appeared to the victim to be a knife. At that point, the victim gave the robber more than $500 in cash. The robber then left the scene on foot, and may later have used a dark-colored SUV to flee, the release states.

The victim said the robber stood 5-feet, 6 or 7 inches tall and was a white man in his late 20s or early 30s. The robber also had facial hair, the release states.

Anyone with information about this case is asked to call JPD at 500-0600.
