On Friday, police said that two rifle bullets were sent to Greek central bank chief Giorgos Provopoulos in a mailed envelope. They added that the bullets, along with a threatening letter, were posted by a previously unknown group called People's Punishers.
Though no further details were given about what exactly the letter said, it became known that a similar envelope also containing two rifle bullets was sent to a prominent journalist from the Greek TV station Mega.
Attacks against politicians, business leaders and journalists have increased of late amid growing public anger at a wealthy elite widely blamed for the nation's protracted debt crisis.
Link to corruption affair?
The head of the central bank is currently associated with a corruption affair surrounding the former Hellenic Postbank.
Last week a prosecutor filed charges against 25 businessmen and officials from the defunct state lender over bad loans the bank issued between 2008 and 2012.
The Greek banking sector experienced a complete overhaul in 2013 in the wake of a recapitalization program supported by the European Union and the International Monetary Fund (IMF). Hellenic Bank was taken over by the privately run Eurobank as a result of the restructuring scheme.
