Hawaii island police are asking the public for help in identifying a suspect in an alleged armed robbery at a Hilo pharmacy.

The robbery took place Monday at around 9:45 p.m. at a business on Puainako Street, the Hawaii Police Department said in a news release. Callers reported a masked suspect with a firearm who allegedly entered the store and demanded prescription medications.

He then left in an SUV-type vehicle, possibly a sliver Nissan, HPD said.

The suspect is described as being “stocky,” between 5 feet, 6 inches tall. He was wearing long pants, a long-sleeved shirt and a tactical-type vest. His head and face were concealed.

Police are investigating the first-degree robbery.
