Police are appealing for public assistance after a distinctive blue motorcycle was stolen from a South Yarra apartment building last month.
Investigators believe two women and a man drove a van onto a secure car park at the Toorak Road apartment complex about 7.30pm on 23 July.
Once inside they wheeled a blue Honda VT1300 motorcycle into the back of their van and fled the scene.
Detectives have released CCTV images of a man and two women who they believe may be able to assist with their enquiries.
They have also released an image of the bike in the hope someone may recognise it and provide information regarding its current whereabouts.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au
