The man was arrested on the armed forces' shooting range at Tåme in northern Skellefteå municipality.
Norran has been informed that it was FMV's on-site personnel at the Tåme shooting range, a Swedish armed forces' protected area, who arrested the man on Saturday.
– It was our personnel who took care of the person and handed him over to the police. We have security guards who monitor our facilities and operations, says Peter Åberg Linder, the authority's press officer.
How serious was the incident?
– It is serious in the sense that we have handed this person over to the police, and now the police will investigate what happened and the background to it.
Is there any suspicion of espionage?
– That is not something I know about or can comment on. We have handed this person over to the police, and now the police will take over and do their investigation.
One of the FMV's tasks is testing and evaluation, continues Åberg Linder, the agency's press officer.
– We test all the equipment we buy to make sure it works as intended he says.
FMV is a civilian agency that procures weaponry for the Swedish armed forces and has its own test sites, for example in Karlsborg and Vidsel, he continues.
– But sometimes, as with this test, we also borrow the Swedish armed forces' shooting ranges. We have been at the Tåme firing range for a couple of weeks.
FMV has been conducting tests for a foreign customer, in this case the United Kingdom, he says.
– Whether it is their armed forces or a procurement agency, I do not know, but it is the British government.
He notes that FMV's test and evaluation activities are internationally recognized and appreciated for their high quality.
– We often get requests from foreign countries to come here throughout the year, but there is particular interest during our unique winter conditions.
FMV have been on-site for a couple of weeks, and the testing will conclude shortly.
– We have tested equipment for the UK in winter conditions, and also have staff on site to support the United Kingdom in this.
What kind of equipment is it?
"It's British equipment, but I'm not going to go into what was tested or how, but it was tested in winter conditions."
