Four individuals, three men and one woman, are charged with involvement in a planned explosion. Two of them were arrested in July this year at Stockholm Central Station. They were on their way to Luleå with the bomb.

It was on the afternoon of July 10 this year that the police narcotics officers spotted a couple at Stockholm Central Station who appeared nervous. They looked around anxiously, arousing suspicion among the officers.

The officers decide to check the couple; 32-year-old Johannes Nikkinen and 37-year-old Matilda Polusen from Ockelbo.

It turns out that both of them are known to the police from before, especially the man who has been convicted of several crimes.

Evacuated Central Station

When the officers frisk the couple Nikkinen and Poulsen, they discover that one of their bags contains a hard package. When asked about its contents, the couple informs the officers that it is a bomb.

The bag is left at the scene, the Central Station is evacuated, and police technicians are called in.

The package turns out to contain a so-called thermos bomb. It is a thermos containing three kilograms of explosive material.

Headed for Luleå

The couple received the bomb from a 40-year-old man in Stockholm named David Martin. He, in turn, received it from a 35-year-old man in Norrtälje named Enging Kaya.

Kaya has a professional background in explosive material handling and has access to commercially manufactured explosives. He has previously been sentenced to prison for unauthorized handling of dynamite and detonators.

Johannes Nikkinen and Matilda Polusen traveled from Ockelbo, where they live, to Stockholm to pick up the bomb. They were then tasked with traveling further with it to Luleå.

It is unclear what the bomb is intended for and whether Luleå is its final destination.

Charged with Crimes

Now Johannes Nikkinen and Matilda Poulsen, as well as Engin Kaya and David Martin, are charged with serious offenses under the law on flammable and explosive substances and for preparation for serious public endangerment.

“The crimes are serious as the handling has taken place in an environment where the item can typically be feared to be used for criminal purposes. The actions have also been of a particularly dangerous and serious nature,” writes the prosecutor in the indictment.

All the accused deny the charges.
