Milan prosecutors have placed two Iranians living in Italy under investigation and ordered their homes to be searched over alleged threats to compatriots opposed to the Tehran government, judicial documents shows according to Reuters.

According to a nine-page search warrant seen by Reuters, prosecutors suspect the two people of aggravated threats and association for the purpose of terrorism and subversion of democracy.

The case stems from complaints filed by several Iranian citizens living in Italy. In one case cited in the warrant, an Iranian dissident told investigators she had received a phone call telling her she had been sentenced to death for being an opposition supporter and would have her assets in Iran confiscated.

One of the two suspects had an Instagram profile from which death threats were made against anyone hoping for the accession to power of Reza Pahlavi — the exiled son of Iran’s former Shah — the warrant showed.
