Fawkner Sexual Offences and Child Abuse Investigation Team are searching for a man who exposed himself in Coburg earlier this month, Victoria Police say.
Police have been told a 38-year-old Coburg woman was walking through Bridges Reserve around 8.30pm on Monday 12 September.
She encountered a man who turned towards her and exposed himself.
The woman returned to a nearby sporting facility and noticed the man had followed her to the door.
She waited inside with staff until the man left and then left the premises and started walking home.
The woman noticed the same man on Harding Street and called her husband on her phone.
The man then left the area.
He is described as 30-40 years old and was wearing a black cap and blue raincoat with white stripes on the arm.
Anyone with any information is urged to contact Crime Stoppers.
