Police have released a sketch of a man who sexually assaulted a female jogger in Christchurch earlier this month.
The woman has now made a formal complaint to police. She was attacked on December 3 at about 8.15pm, near Lincoln University.
Detective Sergeant Kylie Schaare says police are keen to hear from anyone who can identify the man as they may have information that can assist the investigation.
"Police understand that this unprovoked incident occurred while the victim was jogging on her own in a horticultural area near Lincoln University," Ms Schaare said. "Due to the sensitive nature of the incident certain facts will not be released in order to protect the identity of the victim and to prevent her any further distress."
