The Pima County Sheriff's Department is asking for the public's assistance in identifying a serial robber, according to a news release.
Deputies responded to a robbery at the Walgreens located at 9220 North Thornydale Road on Friday afternoon.
As deputies arrived, they learned that a man entered the store and demanded the cashier give him money from the register.
PCSD says no one was injured in the incident but the suspect implied a weapon.
Detectives believe this is the same man who was responsible for previous robberies in the area.
In the most recent incident, the suspect is described as an African American man wearing a New York Yankees baseball cap backwards with dark sunglasses, a blue shirt, and blue shorts.
Detectives with the Robbery/Assault Unit are handling the investigating and ask anyone with information on the identity and/or whereabouts of the suspect to call 9-1-1 or 88-CRIME.
