The police investigation into tax fraud at Airiston Helmi, a Russian-owned firm based in the Turku archipelago, has been delayed once again.
The National Bureau of Investigation (NBI) said that the investigation into domestic tax fraud will not report until the end of the year, attributing the delay to the large volume of material they need to translate and process.
The parallel investigation into international money laundering, on the other hand, will only report next year.
In 2018 police seized 3.5 million euros in cash, among other assets, when they started the probe into a Russian businessman's properties off the south-west coast.
"We have not previously seen such a large volume of confiscated data, and going through it is a demanding job," said Superintendent Mikko Laaksonen, who is heading up the investigation for NBI.
Laaksonen told Yle's Swedish language regional affiliate that co-operation has worked well with foreign law enforcement agencies, even though there have been delays in harmonising processes.
