Police are investigating a string of incidents where hate-motivated graffiti was seen tagged on a number of stores and a bus terminal in Richmond Hill.
York Regional Police say they were called to a plaza in the area of Yonge Street and 16th Avenue on Saturday, where hate-related graffiti was sprayed onto a grocery store.
Officers say that same day, three other stores in that plaza reported anti-Iranian graffiti on the outside walls of their businesses. Later, police say they were notified of more markings reported at a bus terminal near Yonge Street and Highway 7.

Investigators believe a lone male suspect is behind all four incidents and describe him as being five-foot-10 with a thin build, weighing about 160 pounds with short brown hair.
Police say he was wearing a green, long-sleeve button-up shirt, skinny blue jeans with acid wash on the thighs and black shoes. They add that he is left-handed.
Police are asking anyone with information to contact them at 1-866-876-5423, ext. 6552, or Crime Stoppers anonymously.
