The criminal investigation into the drone found at Iitti in Finland on Saturday continued, said police on Monday.
All of the four drones that have been found in Finland are a different kind and suspected Ukrainian origine, said police in a press release.
The Border Guard investigates the incident as a suspected territorial violation, and the National Bureau of Investigation (NBI) investigates a suspected grossly negligent endangerment.
The objective of the investigations is to establish, among others, whether the unmanned aircraft found in Iitti entered the Finnish territory at the same time as the previously found aircraft. The authorities aim to clarify the matter as the criminal investigation progresses.
“We can say at this point that it is the same kind of aircraft as those found earlier. On the basis of the information that we have received during the criminal investigation, all the four aircraft that have been found are a different kind from the type mentioned in public. They are significantly smaller than what has been described in public,” said Detective Superintendent of NBI Risto Lohi.
“The aircraft that have been found are smaller than what has been reported in public, and it is suspected that they are of Ukrainian origin. It should be highlighted, however, that forensic investigations are still underway, and we are not going to draw any conclusions yet,” said Lieutenant Jyri Siitari of the Border Guards Gulf of Finland Coast Guard.
As the authorities suspected that all the aerial vehicles were carrying explosives, they rendered them safe.
All the debris of aircraft found in Iitti has been submitted for forensic examination.
The deviation of the unmanned aerial vehicles is due to Ukraine's countermeasures in response to Russia's aggression in the war, said police, adding that the deviation of the is possibly due to GNSS interference.
