Toronto police are looking for a woman after a brutal and random stabbing at a downtown Shoppers Drug Mart.

Emergency crews were called to the store, in the PATH system at 66 Wellington St. W., just before 3 p.m. on Friday.

A woman had been stabbed, and remains in hospital with critical injuries.

Police said Monday the suspect, Rohinie Bisesar, 40, is wanted for attempted murder. Investigators also released another photo of Bisesar, and warned the public not to approach her as she is considered violent and dangerous.

Police are asking her to surrender.

Police released more details about the incident on Monday, saying Bisesar brought the knife into the store and stabbed the victim who was on the phone shopping.

Bisesar is well-educated and has ties to the Financial District, but it’s not known where she works. Her family has not come forward.

Adris Pone, a colleague of Bisesar, has known her for about a decade and describes the allegations as shocking.

“The behaviour that is alleged is extremely, extremely out of character for Rohinie. (I’m) absolutely shocked. This is someone who is very gentle, very calm, very measured. She speaks almost with a whisper. Physically she is like 5’1 in heels, probably 85 lbs. soaking wet.

“This is someone very gentle, just makes this whole thing all the more surprising.”

Police are not releasing the name of the victim but did say she was “significantly” younger than the suspect. There is no known relationship between the two women.
