Detectives from the Ballarat Crime Investigation Unit are appealing for witnesses following an attempted armed robbery in Ballarat on 4 October.
The incident occurred when the victim, a 30-year-old Ballarat man, was walking on Latrobe Street towards Trekardo Park when he was approached by another man about 2am.
The man demanded the victim hand over his mobile phone which he had been carrying in his hand.
