In early June, two thermos bombs were placed outside the Israeli arms manufacturer Elbit Systems' premises in Gothenburg. Two days later, another explosion attempt occurred there.
The company had previously been warned by Israeli and Swedish security police, confirms the company's CEO in Sweden, Tobias Wennberg, to P4 Gothenburg.
We were aware of an increased threat level without having any details about it, he says.
Last week, three people were charged with involvement in the explosion attempts.
Tobias Wennberg tells in the preliminary investigation that Elbit Systems had been informed a week earlier that there were signs of a violent act being directed against the company.
We were not prepared for what actually happened, but that we should take precautions for an increased threat level was something we were aware of for a short time, he says.
The company was also subjected to a shooting in early October. A boy under 15 years old is suspected of having fired the shots, while two more people are suspected of being involved.
