No one can say for sure how much explosives have disappeared from construction sites because such thefts lack a criminal code.

But a quarter of the explosive substances analyzed by the National Forensic Center have been civilian explosives.

- Swedish construction sites are one of the places where explosives are used. It is important that there is improved supervision, says Linda Staaf, head of the intelligence unit at the Police National Operations Department.

The construction industry claims that most people take responsibility, but thefts can occur.

- When handling large quantities of explosives, it is very easy, for example, for any employee of the company to take explosives with them improperly, says Jan Johansson, CEO of the explosives contractors.

Want to introduce controls

To reduce the risk of explosives coming into the wrong hands, better controls on staff are required.

- It should be a requirement from the legislature that you have register control so that you do not employ criminal people, he says.

Will you work to introduce such controls?

- It's something we will recommend, yes.

Today, it is the municipalities that issue permits and carry out supervision. But there is a lack of knowledge, says Jan Johansson.

- It's totally non-existent.

Missing explosives are not reported

SVT Nyheter also has information from within the construction industry that several kilos of explosives can be missing in major projects without being alerted. Therefore, there may be a dark figure for how much explosives actually disappear because companies do not report concerns about risking permits and assignments.

" It's like shooting yourself in the foot by reporting a theft in that way," says Jan Johansson.

Do you think it happens that companies therefore fail to report?

- It's pure speculation, but I would think so, of course.
