Hacktivists have published a dossier of personal information on the head of Citigroup in retaliation for the cuffing of protesters at an Occupy Wall Street demo.

Members of a group called CabinCr3w, a hacking gang affiliated with Anonymous, revealed phone numbers, an address, email address and financial information on Vikram Pandit, Citigroup's chief executive officer.

The exposé follows the arrest of a group of anti-capitalist protesters who allegedly sparked a ruckus inside a Citibank branch while withdrawing funds and closing their accounts. About 24 people were detained and charged with criminal trespass on Saturday afternoon, The Wall Street Journal reports.

In a statement, Citibank said only one of the protesters was actually trying to close an account, a request that it said was accommodated. The rest of the group were causing a nuisance and were repeatedly asked to leave before the New York City plod were called.

Last week Citigroup supremo Pandit offered to meet protesters, telling Businessweek that their sentiments were "completely understandable".

CabinCr3w previously published the personal information on the chief executives of JP Morgan Chase and Goldman Sachs. It also published the details of an NYPD officer accused of pepper-spraying Occupy Wall Street protesters.

The Citibank branch hubbub, whatever the rights and wrongs of what actually happened, has spawned a new campaign within the Occupy Wall Street umbrella. Op Take Back is encouraging people to close their accounts at high street banks and deposit their money with credit unions instead. ®
