Christchurch police have released an image of a man suspected to be involved in an attack on a 19-year old female at Jellie Park, Burnside, on Sunday.
The composite image has been based on information provided by the victim, who was further interviewed by police yesterday.
The alleged offender is described as being a male, possibly European, with dark facial hair. He was reported to be wearing dark clothing at the time of the incident.
