Activists connected to the Occupy Wall Street protests have published the name, phone number and family details of a senior New York police officer they accuse of using pepper spray on peaceful female protesters at a march on Saturday.
The officer was named in Twitter posts and on various activist websites as NYPD deputy inspector Anthony Bologna, of Patrol Borough Manhattan South.
The posts also cite an apparent civil rights charge against the officer dating from 2007.
YouTube footage of the incident, which has been widely circulated since Saturday, appears to show a white-shirted NYPD officer firing the spray into the eyes of the protesters, who are penned in by other officers with orange netting. As the officer walks away, two of the women crumple to the ground, screaming in pain.
There were several clashes between protesters and police at the march in the financial district on Saturday, during which there were 80 arrests.
Hacker collective Anonymnous claimed responsibility on Monday for posting Bologna's details, which they said was in retribution for the attack.
