An expensive Italian sports car allegedly obstructing a building site has been flipped on its roof by a forklift.

Ninemsn.com reported that the dark blue Maserati 3200 GT, parked next to a construction zone in one of Sydney's affluent eastern suburbs, allegedly blocked access to the site.

A construction company labourer tried to shift the car using a forklift. Unfortunately, the car wobbled off the forks and flipped mid-air before landing on its roof.

Police said the labourer, who ran from the scene, may be charged.
