Police are investigating a robbery that occurred early Saturday in upper Puna.

A 67-year-old Volcano man told police that he was filling water containers at the county spigot station in Kurtistown at about 3 a.m. when he was confronted by a man. The suspect started a conversation with the victim and then allegedly assaulted him and took his wallet.

The man told police that he then observed another man rummaging through his vehicle.

Both suspects fled the scene on foot.

The victim was treated at Hilo Medical Center for non-life-threatening injuries and released.

One of the suspects was described as a Caucasian male in his late teens or early 20s, about 5-foot-9 with a medium build. He may have been wearing light-colored board shorts and a T-shirt.

The case has been classified as a second-degree robbery and first-degree unauthorized entry of a vehicle.

Anyone with information on the incident is asked to contact Det. Joel Field at 961-2381 or via email at jfield@co.hawaii.hi.us.

Anonymous calls can be made to Crime Stoppers at 961-8300.
