Police are investigating an armed robbery at Elias convenience near downtown Windsor.

It happened around 8:30 p.m. Wednesday night at the corner of Dufferin Place and Shepherd Street East.

Police say a suspect entered the store with his identity concealed with dark clothing. He demanded money while brandishing a knife and took a quantity of cash.  At one point the employee struck the suspect on the arm with a baseball bat. It's unknown if the suspect was injured as a result of being stuck by the bat.

Windsor police const. Andrew Drouillard tells CTV News a witness observed the suspect getting into the passenger's seat of a dark coloured car which was waiting nearby.

The suspect was described as a white man, 5'8-5'10 with a thin build. At the time of the robbery, he was wearing a black hoodie with green monster energy drink logo, black sweatpants, gray running shoes with white soles and a balaclava covering his face. 

The store has been the site of a number of robberies dating back to 2015, including an armed robbery in May, 2017 where suspects entered the store with a handgun and a knife.
