On the same day police said they believe the same man is responsible for three sexual assaults, they released information about two other, separate, investigations.
A 20-year-old woman was on a TTC shuttle bus heading east on Bloor Street, near Sherbourne Street, when she was allegedly sexually assaulted.
It happened around 10:15 p.m. on June 4, police say.
The suspect was wearing a white chef coat with two rows of buttons down the front, dark pants, black baseball cap and carrying a black-and-grey backpack. He is 25 to 35 years old, five-feet-eleven-inches to six-feet tall, with a medium build. He had short black hair and a clean-shaven face. Police released photos of the suspect.
Meanwhile, police are investigating reports of a man exposing himself at the East Don Parklands.
The park is located near Leslie Street and Sheppard Avenue.
The suspect is white, in his early 20s, with a stocky or obese build. He has a fair complexion, a brown brush-cut, a round face and red lips. He is always seen with a tablet and a skateboard. He was last seen wearing a red T-shirt and blue shorts.
Police have not said what dates the alleged sex assaults occurred, and they have not released a photo of this suspect.
Anyone with information is asked to contact police.
