Supreme Court prosecutor Yiannis Tentes issued a circular informing authorities on Tuesday that they are within their rights to detain members of Parliament if they are seen committing felonies.
Tentes issued the notice after police failed to react when three Golden Dawn deputies took part in two recent raids at open-air markets and attacked stalls operated by migrants.
The incidents are being investigated and the three lawmakers face having their immunity lifted.
Tentes?s missive said that police have the right to intervene and stop parliamentary deputies even if their immunity has not be lifted.
The prosecutor said that authorities only have to wait for MPs? immunity to be lifted if the offense is considered a misdemeanor.
