The search for anti-war protesters wanted over ugly clashes outside a controversial Melbourne weapons expo has stepped up.
Images of eight people - seven men and one woman - have been released following the unrest triggered by the Land Forces expo on September 11.
Rocks, projectiles, liquids, horse manure and eggs were hurled at officers, horses and expo attendees, police say.
Twenty-seven officers were injured and about 12 horses were exposed to various substances.
"Several police horses and riders were splashed with a liquid irritant including being sprayed under face protectors, going into their mouths and nostrils, and were repeatedly pushed and hit with plastic crates," Victoria Police said in a statement on Wednesday.
Riot officers returned fire on the 1500 demonstrators with rubber bullets, tear gas and flash-bang devices.
Activity over the following two days of the expo was less volatile.
Eighty-nine people were charged or issued fines, with police setting up an investigative team to track down more offenders.
They have also released an image of a man wearing a blue shirt and keffiyeh after a council bin was set alight on Spencer Street.
Chief Commissioner Shane Patton defended his officers' use of force against the protesters, who he called "a bunch of hypocrites".
"They come here to protest against anti-war, so presumably, anti-violence," Mr Patton said at the time.
Senior Victorian minister Danny Pearson heaped scorn on the wanted protesters.
"They should come forward and they should face the consequences of their appalling behaviour," he told reporters on Wednesday.
