Knoxville police continue to investigate an armed robbery last Thursday at an East Knoxville store.

KPD said a man went behind the counter at a Dollar General Store at 2265 McCalla Avenue with a gun, demanding the clerk to open the register.

In the video released by KPD Tuesday, the suspect violently and repeatedly hit the 58-year-old man repeatedly with the handgun before smashing the register and taking the drawer. KPD said the clerk had to be taken to the hospital for his injuries.

KPD described the suspect as a 5' 8" tall black man with a buzz cut. The suspect kept his face hidden during the robbery with a gray hoodie.

The man ran away on foot. Anyone with information is asked to call KPD's crime line at (865) 215-7212. Callers can remain anonymous.
