About 6.45 on August 11, a man entered the Dudley Park Deli in Coodanup and grabbed a female staff member by the arm and demanded she open the cash register.
He was disturbed by a male staff member and left the scene empty handed.
The man was wearing khaki pants, a long sleeved cream coloured hooded jacket, black gloves and black shoes.
He had covered his face with a white mesh mask and had a grey backpack.
Anyone who believes they can identify the man or assist with the inquiries should call Crime Stoppers on 1800 333 000.
DETICTIVES from the Regional Investigations Unit are calling for the public’s assistance into a robbery that occurred in Dudley Park earlier this year.
