Cops last night arrested three self-proclaimed anarchists who assaulted two police officers and terrorized patrons at an East Village coffee shop, authorities said.
The melee broke out at 8:45 p.m. when a gang of 25 authority-haters, some wearing masks, wielded 8-foot-long metal pipes and tried to smash the windows of the Starbucks at Astor Place and Lafayette Street, police said.
Coffee drinkers hid under tables during the fracas, cops said.
The group had just left the sixth annual anarchist book fair being held at a church off Washington Square Park.
They then took to the streets marching against traffic chanting, “F--- the NYPD!” “Cops are murderers!” and “All pigs must die!” authorities said.
In addition to the Starbucks vandalism, a group of about 150 were seen tipping garbage cans and spray-painting anarchist symbols on storefronts, sources said.
One sergeant spotted Eric Marchese, 24, smashing windows at several stores in the East Village, police sources said. He was charged with criminal mischief and disorderly conduct.
Two other protesters, Alexander Penley, 41, and Nicholas Thommen, 30, were slapped with several charges including assault, criminal possession of a weapon and inciting a riot.
At least two of the three 'anarchists' had records of prior arrests in other states, sources said.
Penley, 41, was arrested in Boise, Idaho for allegedly breaking into a US Military processing station.
He'd also been busted in California for burglary, in Oregon for resisting arrest and in Utah for pot possession.
Marchese, who has a New York taxi driver license, had been arrested in New Jersey for improper behavior.
An NYPD sergeant and lieutenant were treated for minor injuries following the incident.
