Detectives from Box Hill Crime Investigation Unit are appealing for public assistance to help solve an aggravated burglary which occurred in Nunawading last month.
Investigators have been told a man entered a home on Springvale Road about 11.40pm on Monday 15 January by forcing open a kitchen window.
The man made his way upstairs but was confronted by a resident.
The offender then ran from the property and was last seen running north along Springvale Road.
He is perceived to be Caucasian, approximately 183cm tall, solid build with medium-length curly brown hair, blue eyes and was only wearing a pair of shorts.
Investigators have released a computer-generated image of a man they believe may be able to assist with their enquires.
