Kennewick business robbed twice in one week.
Kennewick Police are investigating a second robbery at a convenience store this week.
Officers say a man walked into the Jet Mart on Volland just off of Canal Drive at about 9:00 pm.
In both Thursday night's robbery, and a previous robbery on Sunday night, the suspect threatened a clerk with a knife, and wore similar clothing. However, the suspect in Thursday night's robbery has a different build and height.
Police say no one was hurt, and the suspect fled with some cash.
Anyone with information about the robbery is asked to contact Kennewick Police.
