"It's quite possible. He was one of the main shareholders," Jucevičius said in an interview to the daily Lietuvos Rytas. He added that the investigation has not yet advanced far enough to bring suspicions against any persons.
"Members of the management and supervisory boards are also responsible for the bank's activities," the official said.
Jucevičius said that the pre-trial investigation will likely take time.
"The process is not going to be short. It's not some ordinary private limited company. It's a bank. We'll have to make requests for legal assistance to more than one foreign state. The investigation into the bank Snoras has shown that it does take time before answers to such requests come," he said.
The Lithuanian Prosecutor General's Office launched the pre-trial investigation into possible large-scale embezzlement of assets at Ūkio Bankas in February, based on information provided by the central Bank of Lithuania about suspicious transactions concluded in 2005 through 2012.
On February 12, the authorities suspended Ūkio Bankas' operations and on February 18, declared the bank insolvent and permanently revoked its operating license. The "good" part of Ūkio Bankas was later transferred to Šiaulių Bankas. The "bad" part should be declared bankrupt soon.
Romanov held a 65-percent stake in Ūkio Bankas.
