A grassfire in Melbourne's west that saw dozens evacuated from their homes and properties damaged is being treated as suspicious with police seeking a man in relation to the blaze.
The flames burned through grassland at Taylors Lakes and Calder Park on Monday just after 3.30pm when a paddock caught fire.
Investigators have released CCTV of a man on a bicycle who they are trying to identify in the hope he may be able to assist with inquiries.
