The European Central Bank threatened to take legal action against Slovenia on Wednesday after police seized documents from the country's central bank in a rare conflict between authorities and one of the eurozone's most respected institutions.
ECB President Mario Draghi said he deplored the seizure, which infringes on the ECB's legal privileges and immunities, and called on European Commission President Jean-Claude Juncker to intervene.
Slovenian police conducted an investigation Wednesday in four locations in Ljubljana, including at the central bank, collecting evidence in a pre-criminal investigation related to possible irregularities during a bank overhaul in 2013.
"Seized equipment contains ECB information and such information is protected under directly applicable primary EU law," Draghi said in a letter to the Slovenian State Prosecutor General. "The ECB will also explore possible appropriate legal remedies under Slovenian law."

The ECB said police seized information on the computers of Bank of Slovenia Governor Bostjan Jazbec, who sits on the ECB's rate-setting Governing Council, as well as a former deputy governor and some staff members.
Slovenian police said the investigation related to an assessment of one of the banks rescued by the state in 2013, which meant the bank could scrap its obligations toward holders of subordinated bonds and subordinated debt in the value of 257 million euros.
In 2013, the previous government had to pour more than 3 billion euros ($3.33 billion) into local banks to prevent them from collapsing under a large amount of bad loans. The move helped the country narrowly avoid an international bailout.
As part of the bank overhaul, about 600 million euros of subordinated bonds were scrapped in five banks.
In 2014, the Slovenian Association of Small Shareholders filed several court cases against the Bank of Slovenia and local banks, claiming the subordinated bonds and shareholders' capital in rescued banks should not have been erased. None of the cases have been finished yet.
The Bank of Slovenia had repeatedly rejected allegations that it mishandled data used when putting together a rescue package for Slovenia's banks.
