VIDEO: Melbourne building workers converge on Grocon picket line after police attack

Thousands of building workers have left worksites across the Melbourne CBD to support a picket line at a Grocon site after police tried to violently break it up this morning.

Police used capsicum spray and horses on the Construction Forestry Mining Energy Union picket line. The picketers held their ground and the police retreated once more building workers started to arrive.

Below is footage taken at the picket line, at the intersection of Lonsdale and Swanston Streets, by Geelong Trades Hall Council secretary Tim Gooden.
